Britney Spears is three times a lady when it comes to the new music video for her single, "Womanizer."
In the video, which made its worldwide premiere on ABC's 20/20 and can be viewed on britneyspears.com, the pop star shows off her newly buff body and does a little role play – as a wife, a working woman and a sexy waitress.
"Womanizer" is the first single off Spears's upcoming album, Circus, which is due out on Dec. 2 – the pop star's 27th birthday.
