The former 'X Factor' judge, 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', reported OK! magazine.
"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," she wrote.
The group relaunched its official website last Tuesday and reports suggest Cole, 29, and her bandmates will stage a comeback at the Royal Variety Performance at the Royal Albert Hall in London on November 19.
They last released an album in 2008. Their comeback single will benefit BBC's UK charity Children In Need.
