Girls Aloud Comeback Single Leaked On Web

Girls Aloud's long-awaited reunion announcement has been pre-empted by the apparent leaking of their comeback single online.

Club-style track Something New was posted up on YouTube - where thousands of fans got the chance to hear it before it was pulled from the video-sharing site.

The lyrics for the uptempo song are claimed to be: "Go girls go go go go/ We girls gonna take control/ You boys better know know know/ We girls gonna run this show.

"All I want is something new/ Something I can hold on to/ I don't wanna talk/ I just wanna dance/ Baby let it drop/ Catch me if you can."

An official announcement of a tour and greatest hits album is expected on Friday.
