The five-time Grammy winner previously was married to music producer Robert "Mutt" Lange, while Thiébaud is divorced from ex-wife Marie-Anne Thiébaud.

The two reportedly started dating in 2009 following allegations that their then-spouses were having an affair. Each has a child from their previous marriage.

Twain, one of country music's top-selling artists, is set to star in her own TV show, Why Not? With Shania Twain, for the newly launched OWN: The Oprah Winfrey Network. She also recently signed a book deal with Simon and Schuster's Atria Books to publish her autobiography.
