Shania Twain Engaged to Ex-Husband of Woman who stole her Ex-Husband Talk about shocking romantic switches that only happen in the movies! After Shania Twain was cheated by her husband of 14 years, Robert ‘Mutt’ Lange, over her ex-BFF Marie-Ann Thiebaud, the singer is now happily engaged with Thiebaud’s ex-husband, Frederic Thiebaud.Due to their depressions over their ex-hubbies, the two turned to each other for support. This unlikely friendship blossomed until the two got finally hitched. Frederic is a 40 year old Swiss business executive working in Nestle. Twain announced that he asked her to marry him two months ago while they are in Switzerland.The engagement, however, became only known to the public after Twain showed up in New York wearing her engagement ring. Lange left the singer two years ago after he had supposedly fallen for Marie-Ann who was, ironically, Twain’s best friend. During that time, Marie-Anne denied that she was the cause of the divorce, saying that there are a lot of factors and that she is not the sole reason of the couple’s falling apart.Soon after the scandal, Frederic and Twain were seen travelling around the world like in Canada and Florida. The two denied their relationship at first, saying that they are just friends who can relate to each other. In summer 2009, however, Twain finally admitted that they have a deeper kind of relationship in her official website.
