Christina Aguilera Shakes Her Ass. A Lot.

For those of you who have been seeing trailers for Burlesque -- starring Cher, Stanley Tucci, Christina Aguilera, Kristen Bell, and the dude with the funny name -- and sort of hoping it'd be more than just a big honking musical, well, I'm sorry. It seems fairly apparently now that it's going to be a big song-and-dance number kind of movie. Really big.

Here's the first full-length clip released from the movie, of Ms. Aguilera singing "I'm a Good Girl," shaking her ass and spreading her legs. That's actressin', folks.
