Here’s an interesting path to marriage: After Shania Twain’s ex-husband, Robert Lange, left her for her best friend, Marie-Anne Thiébaud, the country star is now engaged to the man Thiébaud left for Lange, Frédéric Thiébaud. “We leaned on one another through the ups and downs, taking turns holding each other up. We've become stronger and closer through it all,” Twain has said of Frédéric. The two became friends after their marriages simultaneously fell apart, and in 2009 they admitted publicly that there was more to their relationship than the purely platonic. A wedding date has not yet been set. Twain and Lange have one son from their marriage, a 9-year-old named Eja.
