Girls Aloud have released a teaser for their upcoming video, set to be released this Friday. The trailer shows the five ladies walking away from the camera and cuts off just as they are about to turn. The new video comes following the announcement of the girl group's long awaited reunion after years of separation. Preparation for the long awaited Girls Aloud reunion is in full swing and the five members are about to make a big announcement to fans on YouTube this Friday.

According to Digital Spy, Cheryl, Nadine, Kimberly, Sarah and Nicola will also be releasing a Greatest Hits album next year, followed by a UK tour, which might turn out to be their last.

The Girls Aloud official website has been relaunched as part of the promotional effort. It features a ten day countdown to the release of the new single "Untouchable".

This isn't the first time the girls have come together after the split in 2009. They interrupted their hiatus later that year to support Coldplay in two shows. On October 7th, this year, the Girls Aloud ladies came together again to perform in Cheryl Cole's solo show A Million Lights in the O2 Arena in London.

The new track was initially rumored to be due for release in November, but the interest in the band's reunion has apparently caused the record label to move up the release date. Whatever the future holds for Girls Aloud, fans are sure to be happy over the oncoming storm of news around the band.
