The demo version of Christina Aguilera's new single 'Your Body' has leaked online. Check it out below.

The single, is a pounding, mid-tempo r&b / electro track with a trace of dubstep in the track's middle eight. The chorus features a surprisingly sexual line from the mum-of-one as Christina sings 'all I wanna do is f*ck your body'.

The track is the first single from the star's seventh studio album. It will be her first release since her previous album, 2010's Bionic, proved a massive flop for the star. She has since made a name for herself in the US as a mentor on The Voice USA.

The singer has been tweeting cryptic shots from the video shoot for the 'Your Body' single, including her wardrobe and her shoes - but now we have a taste of what the single will sound like.

The singer has struggled of late with her public image after rumours of a feud with fellow The Voice judge Adam Levine emerged. He later denied the rumours. The singer also angered British boyband The Wanted, who claimed the singer was 'a bitch' to them when they met in the US.
