If there's one thing Britney Spears knows how to do, it's how to give good vid. The pop star seems to be back in top form in the video for her new single, "Womanizer." Brit rocks three different looks for her girl anthem, everything from herself in a revealing bathrobe to a sexy secretary in a short bob to a leather-clad waitress. The video will premiere this Friday on an unlikely forum, ABC's 20/20. Brit's newest album, Circus, is scheduled for release on her birthday, December 2.
