Shania's Double Betrayal

After a devastating split from her husband of 14 years -- which, a source tells People, "came out of left field" -- Shania Twain is dealing with more heartbreak -- the loss of a good friend. As a picture from People magazine suggests, the woman allegedly behind the country crooner's divorce from her producer hubby, Marie-Anne Thiébaud, was someone who Twain considered a good friend. Not unlike a typical country heartbreak song, Mutt and Marie-Anne are reportedly having an affair, which fueled the musician couple's divorce. Marie-Anne has been a longtime friend of the pair, serving as secretary and house manager at Twain and Lange's Swiss retreat. "Their two families would vacation and spend holidays together," says the source. "Shania considered Marie-Anne one of her best friends." (link)
