Britney's new single - what do you think?

Britney Spears' eagerly-awaited new single 'Hold It Against Me' made its debut on Monday and it's a bass-heavy beast of a comeback from Ms. Spears.

The single is released on February 20th and you can listen to a clip of the song below.

The track is produced by Spears's long-time collaborators Max Martin and Dr. Luke. It's the official lead single from her as-yet-untitled seventh album, due out in March.

She will be shooting the vid this week with X Factor choreographer Brian Friedman directing the moves.
