Singer/songwriter Shania Twain made a spectacular appearance at this year’s Country Music Awards looking fabulous after split from her husband of almost 15 years, idiot music producer Robert “Mutt” Lange.

Shania seems to be completely over it and was seen happily arriving from Switzerland for some Christmas shopping in New York with a group of friends. The group included triathlete Frédéric Thiébaud, who stayed pretty close to the singer while being snapped by the paparazzi. Shania was all smiles after a long plane trip!!

Ironic!! Mutt was cheating Shania with secretary and house manager at Shania and Mutt’s Switzerland estate, Marie-Anne Thiébaud, who was (and apparently still is!!?!) married to Frédéric. Wow! Is it possible Shania is really dating her ex-husband’s mistress’ husband!?!? Or did the betrayal by their former life partners brought them closer together!?!
