UPDATE: Girls Aloud have since denied this rumour. They released a statement today saying:

‘The story is completely fabricated. As Girls Aloud, Nicola Roberts, Sarah Harding, Kimberley Walsh, Cheryl Cole and Nadine Coyle have become one fo the country’s best love groups,’ said a statement released this morning.

‘They have no desire to change the line up. Over the last six years they have scored a record breaking 17 top ten singles and performed three sold-out arena tours around the UK.

Girls Aloud, Britain’s biggest girl band, are reportedly planning to go all Pussycat Dolls and recruit a sixth member of their band through a reality TV show.

The five current members, including X Factor judge Cheryl Cole, will all sit on the judging panel of the show in which they audition hopefuls and grant one the chance to appear live on stage with the band.

A tv insider told The Mirror:

“The winner will get to perform with the group on stage during a one-off concert, but the girls hope they’ll be able to discover a hidden talent who could join the band as a fully paid-up member.

It kind of makes you wonder if one of the girls is planning to leave the group. Maybe Cheryl wants to become a TV judge full time, or maybe Nadine wants to move to LA and chase some more Hollywood actors.
