Christina Aguilera's new single leaks

Singer Christina Aguilera's much-anticipated new single Your Body has leaked online.

The Dirrty hitmaker was set to drop the track, produced by Max Martin, next month (Sep12), but it hit the internet unexpectedly on Friday (24Aug12).

It is not yet clear if the song is a rough cut or the finished version of the song, but the racy tune leaves little to the imagination - the 31 year old can be heard singing, "All I wanna do is f**k your body, tonight's your lucky night I know you want me."

Aguilera filmed a music video for the tune earlier this week (begs20Aug12) and she teased fans by posting a sneak peak of her outfit on Twitter.com - an image of a bright pink platform shoe.

Your Body is due to be featured on Aguilera's forthcoming, as-yet untitled album, expected to be released later this year (12).
