Girls Aloud are reuniting for a comeback single and have already filmed the video for the track, which is rumoured to be released next month.
The Biology hitmakers - who returned to the recording studio earlier this year after going on hiatus in 2009 - met up yesterday (02.10.12) to shoot the promotional clip for a song which will be released next month.
A source told the Daily Mirror: "On Tuesday, all five were together to film the video for their big return song, which is due out next month.
"It was the last possible opportunity they would all have to get together in time for the release, as Cheryl [Cole] has been busy rehearsing for her tour and Kimberly Walsh's training schedule for Strictly [Come Dancing] has been getting more intense."
It is believed to be the first time the five girls - Cheryl, Kimberley, Sarah Harding, Nicola Roberts and Nadine Coyle - have worked all together when they were recording the new songs.
The insider added: "The girls recorded tracks with their long-time collaborators Xenomania as early as May this year.
"Some of them recorded their vocals separately, so they didn't actually see each other that much during the process.
"Obviously, Nadine has been pretty estranged from the group during their time off, too."
The group celebrate their tenth anniversary this year.
