Shania Twain's Best Friend Stole Her Husband

As with any of these music documentaries, take it with a grain of salt because there's a lot of fiction baked into the story.

This biographical video details the devastating betrayal that nearly ended Shania Twain’s career: at the peak of her global success, her husband and longtime producer Mutt Lange began an affair with her trusted best friend and assistant, Marie-Anne ThiĆ©baud. Shania had confided her marital struggles in her friend, only to discover the ultimate double betrayal, which left her so shattered she stopped singing for over a decade, lost her voice to Lyme disease complications, and withdrew from public life. The story covers her humble, abusive childhood, meteoric rise, the painful fallout, and her eventual resilience—remarrying the ex-husband of her former friend in a twist of poetic justice.
