The ex-Sugababes have posted the video for 'Boys' on YouTube.
> Digital Spy's most anticipated albums of 2013
A 3-second clip of the studio version of the track was also released on Soundcloud.
Mutya Buena, Keisha Buchanan and Siobhan Donaghy played a surprise gig on New Year's Eve - their first show together in over a decade.
At that show, the band performed a cover of Rihanna's 'Diamonds' alongside their own hits 'Overload' and 'Freak Like Me'.
The trio have claimed that their first album together since 2001's Sugababes record One Touch is "a step up" from that album while being "eclectic" and "modern".
A snippet of the studio version of 'Boys' has also been premiered on Popjustice.
