Girls Aloud are to split for good after a 10th anniversary tour.

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

The former X Factor judge Cheryl Cole, who has enjoyed a successful solo career since the group announced a hiatus in 2009, has opened up about the band's plans in her autobiography, Cheryl My Story.

She writes, "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".

The group relaunched its official website last Tuesday and reports suggest Cole and her bandmates will stage a comeback at the Royal Variety Performance at the Royal Albert Hall in London on 19 November.

They last released an album in 2008.

Their comeback single will benefit Britain's annual Children In Need charity drive.
