Girls Aloud are set to reunite for a tour in 2012.
A source told The Daily Star: 'Early next year in pencilled in for the reunion tour. It's going to be absolutely massive.
'Cheryl could be a US superstar by then, if her appearance on American 'X Factor' goes according to plan this autumn, so they want to capitalise on that.
'It'll also be the band's 10-year anniversary in 2012, so the timing is just perfect.'
