When country music icon Shania Twain discovered her 14-year marriage was over, the blow came from the two people she trusted most. Yet, in an astonishing twist of fate, the devastating heartbreak paved the way for the most enduring love story of her life.
In 2008, Twain’s world shattered when her then-husband, legendary music producer Robert “Mutt” Lange, abruptly ended their marriage. Multiple reports soon confirmed that Lange had been having an affair with Twain’s close friend and executive assistant, Marie-Anne Thiébaud.
A Shocking Midnight Revelation
Twain had suspected something was wrong in her marriage, but she never imagined the truth. The breakthrough came from an unlikely messenger: Marie-Anne’s husband, Swiss businessman Frédéric Thiébaud.
Frédéric requested an in-person meeting with Twain after discovering evidence of the affair. When he sat down with the country star and laid out the facts, Twain initially refused to accept it.
“I thought he was crazy,” Twain recalled during a television interview. “I said, ‘You’re exaggerating, or you’re being dramatic.'”
Despite Twain’s initial denial, Frédéric stood firm in his discovery. Facing the reality of the betrayal plunged Twain into one of the darkest periods of her life. In her memoir From This Moment On, Twain admitted there were times she felt like she couldn’t go on, but focusing on her young son, Eja, kept her grounded.
From Shared Grief to Lifelong Romance
In the months following the collapse of both their marriages, Twain and Frédéric began speaking regularly. What started as two devastated spouses holding each other up quickly transformed into a deep, unbreakable bond.
“The person to comfort me was Fred because he had been through the exact same thing,” Twain later shared. “Fred was safe. So it was really a beautiful and perfect friendship.”
Over time, that friendship blossomed into romance. Frédéric courted Twain with thoughtful gestures, from spontaneous dinners to trips in Switzerland. By December 2010, the couple announced their engagement to fans. On New Year’s Day 2011, they tied the knot during an intimate sunset ceremony in Rincon, Puerto Rico, where Twain’s son walked her down the aisle.

Reflecting on her marriage in 2026, Twain called Frédéric her “forever true love,” crediting his patience and open communication for keeping their connection strong. As Twain put it, “This is the love I’m going to grow old with—and it’s a beautiful feeling.”
