Shania Twain: My Divorce Was the Wake-Up Call I Needed

Shania Twain says the breakup of her marriage in 2008 left her devastated – then, finally, empowered.

“I didn’t want to live,” she tells Oprah Winfrey of being told that then-husband Robert “Mutt” Lange was having an affair with her assistant and close friend, Marie-Anne Thiebaud, in an interview airing Tuesday.

Now, the singer says the dissolution of that 14-year marriage was “a very positive thing.” Adds Twain: “I needed the wake-up.”
