Girls Aloud -

Cheryl, Kimberley, Nadine, Nicola and Sarah first came to the nation's attention in 2002, as the winners of Popstars: The Rivals. They were the first all-female group to debut at Number One in the UK and the first band ever to get the Christmas Number One with their first single, 'Sound Of The Underground'. A hard act to follow, but subsequent releases have proved these girls are anything but one hit wonders.
