At 60, Shania Twain Finally Speaks Out About the Affair That Ended Her Marriage
The woman who stole Shania Twain’s husband was not a stranger. She was the closest friend Shania trusted more than anyone [music] else. She was a regular presence in Shania’s home, sharing family meals and witnessing the marriage that so many people admired. But behind the scenes, that same woman had secretly been involved in an affair with Shania’s husband.
Many years later, in an emotional interview with People magazine, Shania Twain opened up for the first time about the heartbreak she had carried with her for so many years. She recounted how Robert Mutt Lange suddenly ended their 15-year marriage and how she discovered that the two people she trusted most had betrayed her behind her back.
In the blink of an eye, Shania lost the husband she loved, the best friend she considered a sister, and the marriage that had once been seen as a fairytale in the entertainment world. Yet it was precisely when she reached the lowest point of her life that her story took a turn no one could have imagined. The betrayal that seemed destined to destroy everything ultimately became the beginning of the happiest chapter of her life.
What really happened behind the closed doors [music] of the marriage that the whole world once admired? And how did Shania Twain transform the greatest heartbreak of her life into an ending even more beautiful than what she had lost? That is the story we will revisit in today’s video. Shania Twain, born Eileen Regina Edwards, was born in 1965 in Ontario, Canada.
Her childhood was marked by poverty and countless family hardships. After her parents divorced, [music] her mother took Shania and her sisters to Timmins, where she later married Jerry Twain, who eventually adopted the children. Growing up in a large family struggling to make ends meet forced Shania to mature at a very young age.
She has recalled that there were days when her family did not have enough food to eat, and they tried to hide their financial struggles [music] from those around them. At the age of eight, Shania began singing to help support her [music] family. Every weekend, her parents took her to bars and small venues where she performed until [music] late at night.
Although she disliked that environment, those long nights of performing [music] helped her develop her voice, confidence, and stage presence from an early age. Besides singing, she also took on many physically demanding jobs to help her parents, building the resilience and determination that would stay with her throughout her life.
In 1987, when she was just in her early 20s, Shania faced the greatest tragedy of her life when her mother and stepfather were killed in a car accident. Instead of immediately pursuing her musical dreams, she put her career on hold to care for her younger siblings. For several years, Shania worked as a singer at a resort in Ontario to earn a living and support [music] her family.
Those difficult years only strengthened her determination to pursue a professional music career. Her breakthrough came in the early 1990s when Shania signed with Mercury Nashville and met producer Mutt Lange. After her self-titled debut album failed to make much of an impact, she exploded onto the music scene with The Woman in Me in 1995 and became a global superstar with Come On Over in 1997.
Songs such as You’re Still [music] the One, That Don’t Impress Me Much, and Man, I Feel Like a Woman made her a household name around the world while helping the album become one of the best-selling records of all time. From a little girl singing in small bars in northern Canada, Shania Twain rose to become the queen of country pop and the best-selling female country music artist in history with more than 100 million records sold worldwide.
Beyond her chart-topping hits and five Grammy Awards, she has also been admired for overcoming poverty, loss, and countless hardships to reach the pinnacle of the global music industry. If Shania Twain’s career is [music] a story of extraordinary success and record-breaking achievements, then the life behind the spotlight was filled with deep emotional scars.
Shania Twain and Robert Mutt Lange met through music in the early 1990s. In 1993, Mutt, the legendary producer who had worked with AC/DC and Def Leppard, heard Shania’s demo tape and reached out to her. They spent hours talking on the phone, exchanging musical ideas before finally meeting in person about 6 months later.
Their first meeting took place at Shania’s home in Canada. Mutt was impressed by her talent and voice, while Shania admired his expertise and deep understanding of music. Their relationship quickly blossomed from that shared professional connection. That moment marked the beginning of a romance that was both deeply passionate and closely intertwined with an extraordinary musical career.
They fell deeply in love and decided to marry after only a few months of dating. Their wedding took place on December 28th, 1993 at Shania’s home in Ontario, Canada. It was a simple, intimate ceremony surrounded by family, and they celebrated with non-alcoholic champagne because Mutt did not drink alcohol. Soon after their marriage, they formed an incredibly successful professional partnership.
Mutt produced The Woman in Me, 1995, the album that launched Shania to international stardom and sold more than 20 million copies. Their marriage was initially seen as a happy union, combining talent and love in perfect harmony. They welcomed their son, Eja Lange, in 2001. Their family life remained relatively private, centered on music and family in Switzerland and Canada.
Shania once described Mutt as her ideal life partner, the man who had helped her heal from the wounds of her past and rebuild her career from the ground up. Then one day, Mutt came home with an unusually cold expression on his face, and just minutes later Shania’s life changed forever. He sat down, remained silent for a long time, and finally spoke.
I can’t continue this marriage anymore. I want to end it. It was only a short sentence, but it brought Shania’s entire world to a standstill. She was stunned, unable to comprehend what she had just heard. What do you mean? What happened? What did we do wrong? Shania kept asking, desperately searching for an explanation.
But the man she loved simply lowered his head in silence, saying almost nothing else. Shania could not believe it was real. Just the day before, she had believed her family was doing fine. There had been no explosive arguments, no warnings, and no signs that their marriage was on the verge of collapse. Everything happened so suddenly, as if someone had pulled the rug out from under her feet.
Only one question echoed through her mind. Why? In utter despair, she looked her husband straight in the eyes and asked [music] through tears, “Do you still love me?” It was the question every wife longs to have answered, no matter how painful the truth may be. But Mutt gave no reply. He simply remained silent. That silence was more cruel than any confession could have been.
It made Shania realize that the man [music] she had trusted for 14 years had seemingly left their marriage long before he ever spoke the words of goodbye. After that conversation with her husband, Shania turned to the person she trusted most besides him, Marie-Anne Thiébaud, the close friend who had been by their family’s side for many years.
Shania called her, broke down in tears, poured out her heart, and begged for advice. She hoped Marie-Anne, who seemed to understand Mutt better than anyone else, could help her figure out why her marriage was falling apart. Yet Marie-Anne gently comforted her, insisting that she had no idea what was going [music] on, and telling Shania that all she needed to do was be patient, and everything would eventually be all right.
Let’s take a closer look at Marie. Marie-Anne Thiébaud was not a public figure. She was a Swiss woman who worked as both Shania Twain’s personal assistant and housekeeper when Shania was married to Robert Mutt Lange. Over the years, Marie-Anne had become almost like a member of the family. She was a constant presence in Shania’s daily life, helping manage the household and becoming someone the singer trusted completely.
As time passed, their relationship grew far beyond that of employer and employee. Shania came to see Marie-Anne as one of her closest friends. Their two families frequently vacationed together, shared meals together, and spent countless private moments [music] in each other’s company.
Marie-Anne’s husband, Frédéric Thiébaud, was also a [music] close friend of Mutt Lange, making the four of them an exceptionally close-knit group. To Shania, Marie-Anne was one of the very few people she trusted without reservation. Yet, that very trust became the thing that wounded Shania most deeply. When she first began noticing unsettling changes in her husband, she turned to Marie-Anne for comfort.
Rather than suspecting her closest friend, Shania believed Marie-Anne would help her understand what was happening. Marie-Anne reassured her that everything was fine, leading Shania to dismiss her own instincts once again. What Shania never knew was that while she was crying to the friend she trusted most, Marie-Anne was the one hiding the biggest secret of all.
Marie-Anne had been secretly having an affair with Mutt Lange for months. The woman who constantly embraced Shania to comfort her, who listened to her tears and heartbreak, was in fact the very person responsible [music] for destroying her marriage. Ironically, the person who finally exposed the truth was neither Mutt nor Marie-Anne, but Frédéric Thiébaud, Marie-Anne’s husband.
He was the first to notice the warning signs: hotel receipts, hundreds of secret phone calls, and eventually a set of lingerie along with seductive accessories hidden inside his wife’s suitcase. It was undeniable evidence. When confronted, both Marie-Anne and Mutt refused to tell Shania the truth. They intended to let the divorce unfold quietly, allowing her to spend the rest of her life never knowing why she had been abandoned.
In the end, Frederic was forced to do what no one wanted to do. A man who had once been almost a stranger had to sit down and tell Shania that [music] her husband was leaving her for her own best friend. At first, Shania simply could not believe it. She refused to accept the truth. In desperation, she called Marie-Anne, hoping her friend would confess or at the very least offer an explanation.
Instead, she was met only with cold denials. A few days later, Marie-Anne changed her phone number and cut off all contact, as though erasing a friendship that had lasted for years. Even more heartbreaking was the fact that when this betrayal happened, Shania Twain was already struggling with a silent illness that threatened her career, dysphonia, or a voice disorder.
It was a consequence of Lyme disease, which she contracted in 2003 after being bitten by a tick while horseback riding. Shania described the symptoms of Lyme disease as truly terrifying. She frequently lost her balance, became dizzy on stage, and experienced brief blackouts that lasted only a split second, but occurred repeatedly every minute or even every 30 seconds.
She wallowed that she had performed at least 10 concerts while in such a dangerous condition, forcing herself to keep her eyes wide open and avoiding standing near the edge of the stage so she would not fall. The illness robbed her of her powerful singing voice, leaving her unable to sing, and there was a time when Shania truly believed she would never perform again.
The relentless series of devastating blows left her feeling as though she no longer had the strength to keep going. Looking back years later, Shania admitted that she often wondered how much more pain one person could possibly endure. She said she did not simply feel hurt. She felt completely crushed. To Shania, this betrayal was the final straw after years of accumulated pressure and emotional wounds.
[music] The pain was so overwhelming that she fell into a long period of depression. There were days when Shania barely cared about tomorrow. For years she lived with overwhelming sadness, emptiness, and an inability to escape thoughts of the betrayal. It consumed her mind to the point where she no longer had the strength to focus on anything other than her own heartbreak.
What made it even more devastating was that the emotional trauma directly affected her singing voice, the most valuable asset of her career. Shania believed that years of living with anxiety and stress had caused the muscles around her larynx to tighten more and more. And that the collapse of her marriage became the catalyst that made the condition far worse.
She not only lost her husband, but also the creative partner who had stood beside her for more than a decade. She genuinely believed that her singing career was over and that she would never again [music] have the strength to raise her voice in song. During her darkest days, Shania almost lost all hope in life.
She admitted that there were periods when she could not [music] get out of bed, did not want to see anyone, and simply wanted to disappear from the world. Shania has said that she struggled deeply with feelings of shame and humiliation after being so openly betrayed, especially by the closest friend she had trusted and regarded as a younger sister.
The double betrayal shattered not only her faith in love, but also her trust in people in general, and it took her many years to gradually heal from those emotional wounds. Everyone who had ever worked with Shania Twain shared the same opinion. She was one of the most sincere and loyal artist they had ever met. Even after becoming an international superstar, Shania still remembered the names of every member of her team, was often the first person to arrive, and treated everyone with respect.
To her, loyalty was not simply a choice. It was the way she lived her life. And it was that same loyalty that she brought [music] into her marriage. For many years, Shania’s entire world revolved around the two people who mattered most to her, her husband, Robert Mutt Lange, and her best friend, Marie-Anne Thiébaud.
She trusted them completely, giving them the most precious parts of her life without holding back even the slightest suspicion. Yet, the cruelest part of all was that, in the end, those two people chose each other, leaving her behind. To preserve her marriage, Shania was willing to sacrifice a great deal. She moved to Switzerland to be closer to her husband, willingly leaving behind the center of the music industry she had once conquered.
She allowed Mutt to be involved in nearly every important decision in her career, from her music and public image to her work schedule. Even as one of the world’s most successful female artists, Shania never publicly complained or insisted on having the [music] final say. To her, protecting her family was always more important than asserting her own ego.
What is remarkable is that Shania had every right to do the opposite. At that point, she had already sold more than 100 million albums, making her one of the best-selling female artists of [music] all time. She had the fame, the influence, and the status to demand anything she wanted. But, Shania never used her success as leverage against her husband.
She never turned her career into a tool for controlling Mutt, because she believed that in a genuine marriage, love should never be a negotiation over who has the upper hand. Perhaps what Shania truly lost after the betrayal was not only her husband or her closest friend. What she also lost was the part of herself that had once trusted others completely.
When you give someone your whole heart, you never imagine that you need to guard yourself against them. But, when that trust is shattered, it is not just a relationship that falls apart. It is also the sense of security you once had in your own life. In 2026, during an emotional interview with People magazine, Shania Twain opened up completely for the first time about the pain of the betrayal that ended her 15-year marriage to Robert Mutt Lange.
Shania said that she had placed her complete trust in Mutt Lange. For years, she had never imagined that he would betray her. Then there was Marie-Anne Thiébaud, the woman she considered family, the person she vacationed with, shared intimate moments with, and never once felt the need to guard herself against.
“I trusted them with all my heart,” Shania shared. “So, when it happened, I felt as though my entire life had been torn in two.” When she received a message from Frédéric Thiébaud informing her about the affair between her husband and her closest friend, she was left speechless. Shania recalled, “I couldn’t believe that the person I loved most was the one who betrayed me so cruelly.
I had spent nearly two decades building a life with him, and it all collapsed in a single moment.” The double betrayal by both her husband and her best friend sent Shania into a deep depression. She admitted that there were dark periods when she barely ate, barely slept, and frequently found herself thinking about the worst possible outcomes.
“There were days when I woke up wondering whether I could make it through,” she said. “I thought I had everything, a happy family, a successful career, and loyal friends, but it all turned out to be a lie.” Shania said she struggled with overwhelming feelings of shame, humiliation, and a complete loss of faith in love. What hurt even more than the collapse of her marriage was the betrayal by Marie-Anne Thiébaud.
Shania explained, “She wasn’t just my assistant, she was my little sister. I shared my deepest secrets with her, my greatest fears, and even my dreams. And she used all of that to betray me.” She had confided in Marie-Anne about her concerns regarding her marriage, and had been reassured that everything was fine, all while the affair continued behind her back.
That deception made Shania feel painfully naive and foolish. Years later, Shania admitted that the pain was almost impossible to put into words. She once said that if she ever had the opportunity to meet Marie-Anne again, the only thing she would want [music] to say was, “I wish I had never met you.” For many years, she deliberately tried to erase the image of her former friend from her mind in order to protect her own mental well-being.
“I spent far too much time grieving,” Shania said. “But I realized that if I kept living in the past, I would never be able to move forward.” In the darkest days of her despair, she never imagined that the only person who could truly understand her pain would be Frédéric Thiébaud, the man who had also just lost his wife because of the very same betrayal.
At first, there was no romance between them. There were only two people with broken hearts who found a rare sense of understanding in one another. Neither of them needed to explain much because they both knew exactly how it felt to be betrayed by the person they loved most [music] and the person they trusted most.
Shania later admitted that it was Frédéric [music] who helped her get back on her feet during the darkest period of her life. By his side, she no longer felt alone because at last, someone truly understood what she was going through. Through long conversations, quiet words of encouragement, and the comfort of each other’s presence, they slowly healed the wounds that others had left behind.
Neither of them tried to replace the other’s past. They simply stayed by each other’s side, patiently helping one another make it through each day. What began as mutual compassion gradually became a unique bond strong enough to heal hearts that had once believed they would never love again. By the summer of 2009, Shania and Frédéric began appearing together during a vacation in Canada.
Accompanying them were not only Shania’s son, but also Frédéric’s daughter. The sight of the two small families spending time together attracted attention, yet they both remained extremely private. When asked about their relationship, Shania simply described Frederic as a close friend and a true gentleman. Perhaps even she had not yet realized that their friendship had quietly entered a new chapter.
Years later, Shania explained that she fell in love with Frederic, not because of grand promises or romantic gestures, [music] but because of the way he faced adversity. She watched him endure heartbreak with calmness, kindness, and dignity. To Shania, that was the image of a truly strong man in the most admirable sense.
The more she observed him, the more she admired him, and before she even realized it, that admiration gradually blossomed into love. For his part, Frederic also admitted that their love story had never been part of either of their plans. They did not come together out of revenge or to fill an emotional void.
Instead, amid the wreckage of their pasts, they unexpectedly found someone who could make them smile again. Their love developed slowly and peacefully, but it was sincere enough to erase the doubts that still lingered. In December 2010, Shania personally announced [music] her engagement on her website with a heartfelt message.
“I am excited to share some personal news with you. I am in love.” Frederic Nicolas Thiebaud [music] has been a true gift to me as a compassionate, understanding friend, and over time, an amazing [music] love has blossomed from this precious friendship. In early 2011, Shania Twain and Frederic Thiebaud officially married in a private ceremony.
For Shania, it was far more than a wedding. It marked the end of the painful years she had once believed would [music] haunt her forever. The woman who had thought she had lost everything finally found happiness again. Not by forgetting the past, but by allowing someone truly worthy to enter her life. Since their marriage, Shania Twain and Frederic Thiebaud have chosen to live a peaceful life away from the spotlight of the entertainment industry.
After everything she had endured, what Shania treasured most was no longer fame or glamour, but the feeling of being loved and at peace every single day. She has repeatedly described Frederic as “my best friend” and has openly admitted, “I can’t live without him. I need that support. I need what we have. It keeps me grounded every day.
” What brings Shania happiness is not extravagant gifts or grand promises, but the small thoughtful gestures her husband makes every day. She once recalled that one morning while she was taking a shower, Frederic had to leave the house but knew she had not eaten yet. Before leaving, he quietly prepared a plate of salad, placed it on a small table, and left behind a handwritten note that read, “I love you, Fred.
” When she stepped out of the shower and saw that simple scene, Shania realized that she had finally found something she once believed she would never have again. A sincere, gentle love that always placed her first. Years after her divorce, as the emotional wounds gradually began to heal, Shania published her memoir From This Moment On.
What haunted readers most was not the details of the affair itself, but one brief statement she made about Marie-Anne Thiebaud. Shania wrote, “I was disgusted that greed to elevate another woman’s lifestyle was considered worth the devastation of my family.” It was the phrase “to elevate another woman’s lifestyle” that left so many readers speechless.
Because in Shania’s mind, this was never simply a story about love or an illicit affair. She believed that Marie-Anne had looked at the life Shania had spent years building through hard work and decided that she wanted all of it for herself. Not only the husband, but also the home in Switzerland, the the lifestyle, the status, the security, and everything Shania had sacrificed her youth to achieve.
What is truly admirable is that Shania never chose [music] revenge. She never went on television to publicly shame her ex-husband or her former friend. Nor did she turn her memoir into a platform for [music] attacking them. Instead, she chose to protect her son, preserve her own dignity, and quietly begin a new chapter of her life.
Perhaps, sometimes the most powerful form of revenge is not making someone else suffer, but proving that you can still find happiness even after they have shattered everything you once held dear. At the age of 60, Shania Twain is enjoying a fulfilling life and a thriving career. She remains a global music icon with more than 100 million records sold and five Grammy Awards.
She has made a powerful return with new music while also embracing a happy married life with her husband, Frédéric Thiébaud. Shania has overcome the serious health crisis [music] caused by Lyme disease. She has shared that she feels healthy and grateful as she enters her 60s, embracing life with abundant energy and an enduring passion for music.
Shania Twain’s career in 2026 is busier than ever with several major projects underway. On July 24th, 2026, she released her seventh studio album, Little Miss Twain, which has been described as the most personal and honest album of her career. The record revisits her childhood and musical roots through a blend [music] of country, rock, and R&B.
It features 15 tracks and includes collaborations with acclaimed artists such as Tanya Tucker, Josh Homme, and [music] The War and Treaty. In addition, Shania is currently serving as the opening act for all 12 of Harry Styles stadium shows at Wembley Stadium in London, running from June 12th through July 4th, [music] 2026.
The opportunity allows her to connect with a younger generation of fans while reaffirming her place as one of music’s enduring stars. She’s also scheduled to headline her own concert at Thomond Park Stadium in Ireland on July 7th of the same year. Beyond music, Shania is expanding into film as a biographical movie about her life titled Shania is currently in development by Sony Pictures.
She will also serve as a producer on the project. The film is considered a deeply personal endeavor that promises [music] to offer an honest and intimate look at the remarkable journey of the queen of country pop. After years of betrayal and losing faith in those she loved most, Shania has finally found peace.
The tears of the past have given way to a life filled with simple moments that are more than enough to warm her heart. Perhaps for Shania Twain, true happiness is not about finding a perfect love, but about finding the right person. Someone who makes her feel cherished every single day. Shania Twain’s story resonates so deeply not simply because of an affair, but because the betrayal came from the two people she trusted most.
The husband who had shared 15 years of her life and the best friend she once considered family. Yet in the end, Shania proved that the most valuable thing is not holding on to a marriage at any cost, but having the strength to rise again after everything has fallen apart. What about you? Do you think you could forgive a betrayal like this? And if you had the chance to start over, would you choose to hold on to the past? Or would you find the courage to move forward as Shania did?
