The long-awaited Girls Aloud reunion is in full flow and the band are finally set to unveil their new single.

A teaser for the video has been released, which sees the five girls walking away from the camera in slow motion - but the clip ends just as they start to turn around.

But fans of the girlband won't have long to wait because the footage also confirms that Cheryl, Sarah, Kimberley, Nadine and Nicola will be making a special announcement live on YouTube this Friday.
