The girl group are expected to unveil the full single and accompanying music video on Friday (October 19).
The clip sees the five-piece walking away from the camera in slow motion and starting to turn around just as the video snippet ends.
The video concludes with the confirmation that Girls Aloud will make a special announcement live on YouTube this Friday.
It is thought the pop act will announce a new Greatest Hits collection and a final headline tour of the UK, after Cheryl Cole revealed the plans at the end of her new autobiography.
Cole also admitted that the retrospective and tour will serve as the girl group's last outing as a five-piece and claimed that they plan to part ways following their tenth anniversary celebrations.
