Heidi's Got The Moves!

Heidi Montag showed off her spectacular dancing abilities in Las Vegas the other night when she celebrated her (belated) birthday at the Christian Audigier Night Club. Her main douche man was there as well, and they posed for a bunch of pictures before heading inside to get their groove on. I know Heidi is skinny, but that's a pretty impressive food baby she's carrying. Or is it a real baby? Or did she simply forgot to suck it in and put on her spanx that night? Hmmmm!
