Christina Aguilera Strips Down for New ‘Burlesque’ Clip (VIDEO)

And here everyone thought Christina Aguilera’s Halloween costume was provocative.

A new clip from Xtina’s big-screen debut, Burlesque (out on Thanksgiving weekend) has been released, and while previously released clips have showcased the singer’s obvious vocal chops, this time viewers also get to see how the newly single songbird fares when she strips down to her sparkly skivvies and does some bump-and-grind on stage.

Check out the sexy clip of Aguilera shaking her stuff and singing “But I Am a Good Girl” below. Do you plan on seeing Burlesque when it hits theaters? Let us know in the comments section.
