[post_page_title]Robert Lange, Shania Twain, and Marie-Anne Thiébaud[/post_page_title]
Though this one started as a love triangle, it quickly turned into a love square and then things just got complicated. Shania Twain had been married to music producer “Mutt” Lange, for 17 years when they announced their separation. Why, you may ask? Lange had apparently been seeing Twain’s best friend, Marie-Anne Thiebaud, behind her back. While things didn’t work out for Lange and Thiebaud, Twain ended up marry Marie-Anne’s former husband in 2011 and the two have been happily together in love since. She sure chose an extreme form of revenge, but it’s pretty understandable given the circumstances.
