Name: Marie Anne Thiebaud
Alleged Mistress to: Gorgeous country singer Shania Twain’s husband, Robert Mutt Lange. (For the record, Marie Anne Thiebaud was Twain’s best friend and the secretary for the couple).
Ooops: Twain divorced her husband, and told the world what Marie Anne Thiebaud did.
Update: Twain found a new husband, Thiebaud’s ex-husband, Frederic. Thiebaud is, of course, no longer employed with Shania.
