The Infamous 'Wife-Swap' Scandal: A Double Betrayal

The end of Shania Twain's 14-year marriage to Mutt Lange was not just a simple celebrity divorce; it was a deeply personal and public scandal that rocked the music world. The couple, who had lived a highly private life in Switzerland with their son Eja D'Angelo Lange, seemed like an unbreakable creative and romantic partnership.

The unraveling began in 2008 when Mutt Lange allegedly confessed to an affair with Shania's long-time friend and personal assistant, Marie-Anne Thiébaud. Marie-Anne was, at the time, married to Frédéric Thiébaud.

The shocking twist is that Frédéric Thiébaud was the one who delivered the devastating news to Shania. He noticed the suspicious behavior of his wife and Mutt Lange and felt compelled to tell Shania. This act of shared honesty and vulnerability in the face of immense heartbreak became the unlikely foundation for their future love story.

Shania Twain has openly discussed the emotional fallout, describing the betrayal as a loss of two of the most important people in her life at once.

Frédéric, a successful Nestlé executive, is often described as Shania's rock. Unlike Mutt Lange, who was a collaborator and a demanding creative force, Frédéric is a steady, non-showbiz partner who offers her unconditional emotional support. Shania has credited him with helping her overcome the emotional trauma of the divorce and the physical challenges of her battle with dysphonia caused by Lyme disease.

A Decade of Happiness and Stability

More than a decade into their marriage, Shania and Frédéric's relationship continues to thrive, a fact often highlighted in Shania's rare social media updates and interviews. She has described their marriage as "beautifully twisted" due to its dramatic origins.

This enduring happiness is fresh proof that even the most devastating betrayals can lead to unforeseen joy. The stability provided by Frédéric Thiébaud has allowed Shania to focus on her career resurgence, including her Las Vegas residency and her Netflix documentary, where she openly discusses the emotional impact of the divorce and her current contentment. This candidness solidifies the narrative that her second chapter is one of triumph over adversity, with her current spouse, Frédéric, as the hero of her personal life.
