Britney Spears recently tweeted, "Heard an early demo of my new single leaked. If u think that's good, wait til you hear the real one Tuesday." That means this song, "Hold It Against Me," is actually her new single.

This demo is an early version sung by the songwriter Bonnie McKee. Everyone involved says it's pretty different now, but the title doesn't seem to have changed. Over/under on how many whisper-grunted "uh uh uh"s Brit added when it was her turn to sing it? [Popeater, @BritneySpears]
