On Set of Christina Aguilera's 'Not Myself Tonight' Video

Christina Aguilera gets down on all fours on the set of her Hype Williams-directed video for “Not Myself Tonight,” the first single from her fourth studio album Bionic, written and produced by Polow Da Don and Ester Dean. The pop star returns to her “dirrty” ways, donning latex outfits, S&M gear, and lingerie, in the racy clip which premieres this Friday.
