Denise Truscello/WireImage.comShania Twain is engaged...to the ex-husband of the woman who allegedly had an affair with her ex-husband. The woman, Marie-Anne Thiebaud, who denied the affair, was also a friend of Shania's, so of course the singer was devastated that Thiebaud was reportedly porking her husband. If you're confused, don't worry so am I. Go watch and episode of One Life to Live and it will become clear. Shania and Marie-Anne's ex fell in love when they reached out to "comfort" each other in the wake of the alleged affair. I don't know if things worked out with their exes, but I hope not. I can't think of a better revenge than living happily ever after with the ex-husband of the woman you were left for. Honestly I would have liked to have seen LeAnn Rimes' ex, Dean Sheremet, find love with Brandi Glanville, Eddie Cibrian's ex. But Dean just got engaged to someone else, who in an interesting twist, is not a man.
