Shania Twain's husband cheats
Country singer Shania Twain was devastated when she discovered her music producer husband Robert "Mutt" Lange was having an affair with her best friend Mary-Anne Thiebaud. She has since admitted that she begged her friend to stay away from him, but Lange and Thiebaud, who was also married, left their spouses to be together. As if that wasn't shocking enough, Twain then found love with Thiebaud's ex-husband Frederic. The couple are now married. It seems this foursome took the TV show Wife Swap a little too seriously!
