Christina Aguilera's 'Not Myself Tonight' video: Has she gone Gaga?

Christina Aguilera is back, and she's not safe for work. Aguilera's last album, "Back to Basics," had a more demure '40s theme, but her new video for "Not Myself Tonight" from her upcoming album "Bionic" has her returning to the raunchy bondage gear that kept her "Dirrty" video at the top of the TRL charts eight years ago.

The video features Aguilera in various fetish outfits. At one point she appears restrained by handcuffs, a diamond ball gag, and a collar, and she spends much of the video in PVC bodysuits. The clip, which highlights plenty of lesbian romps, ends with an implied orgy in a church. Aguilera is fearless, proclaiming, "If you don't like it, f*** you," in the chorus.
