Britney Spears Hold It Against Me ArtFans of Britney Spears can get an unusual sneak peek at her sure-to-be-hit new single 'Hold It Against Me.' While a version of the song has leaked, the blond bombshell is not the one singing on the track.

Singer/songwriter Bonnie McKee is the featured voice on the demo, which was produced by beatmaker Dr. Luke. The bass-thumping track features lyrics like, "If I said my heart was beating loud, if we could escape the crowd somehow / If I said I want your body now, would you hold it against me? / 'Cause you feel like paradise and I need a vacation tonight."

Spears, McKee and Dr. Luke took to Twitter to inform fans that the leaked version was not the final track set to premiere Tuesday, Jan. 11.
