Christina Aguilera’s new single leaks online

The 31-year-old singer has been shooting a music video this week for the single and has teased fans by posting images from the set on Twitter.

Aguilera has also dyed her hair deep purple for a photoshoot which was for the artwork for the new collection.

“Its finally here – Music Video shoot day! Get ready guys!(sic),” she had posted.

The new track is a preview of Aguilera’s seventh album,which will be released this autumn.

The as-yet-untitled record will follow up to 2010’s ‘Bionic’,which was a commercial flop,although Aguilera’s profile was recently boosted when she appeared on Maroon 5’s huge ‘Moves Like Jagger’ single.

She is also a mentor on the US version of ‘The Voice’ and contributed a number of songs to the soundtrack to film ‘Burlesque’,which she also starred in and was a hit,selling over a million copies worldwide.
