Group have shifted 4.3m singles since their 2002 debut 'Sound Of The Underground'

Girls Aloud have become the biggest selling girl group of the 21st century, based on single sales.

The band have racked up sales of nearly 4.3m singles since their 2002 debut ‘Sound Of The Underground’, which sold over 653,000 copies in the UK. The track is also their fastest selling single, shifting 213,000 copies in its first week.

Over the last decade, Girls Aloud have had 20 top ten singles and four Number Ones, according to the Official Charts Company.

Earlier this week (October 16) Girls Aloud‘s comeback single, ‘Something New’ leaked online – scroll to listen to it. The track was set for release today (October 19), but the song – which is their first single since 2009’s ‘Untouchable’ – surfaced online before its official premiere.

Last weekend (October 14), Girls Aloud singer Cheryl Cole suggested that the band’s reunion would be short-lived, as they would part ways again after releasing a greatest hits album and embarking on a 10th anniversary tour.

In her newly released autobiography, Cheryl: My Story, she wrote: “We’ll be working on a tour and greatest hits album. Then I think that’s it for Girls Aloud. We’ve achieved more than any of us ever dared to dream of.”

Girls Aloud originally formed on Popstars: The Rivals in 2002 and went on to have major chart success before going on hiatus in July 2009 to allow band members Cheryl Cole, Kimberley Walsh, Nadine Coyle, Nicola Roberts and Sarah Harding to pursue other projects.
