Britney Spears' "Womanizer" has been getting around almost as much as the track's antagonist.
The Circus starter-single has become the latest pop song to be covered by several other major artists. (Remember when Mandy Moore killed on Rihanna's "Umbrella"?) Lily Allen and the All-American Rejects have both put their spin on the track.
If imitation really is the highest form of flattery, Brit has been well-complimented.
