Britney Spears is set to shock with a handful of saucy alter-egos in her new Womanizer video.

The pop superstar will portray herself in saucy lingerie, a leather-clad tattooed waitress and a racy office employee who suggestively straddles a co-worker.

And the singer wigs out with her new video characters, wearing a different hairstyle for each one.

Her sexy secretary boasts a Katie Holmes-style bob, while the waitress boasts an auburn look.
