Kimberley Walsh claims Girls Aloud will never split up.

The girl band - also including Cheryl Cole, Nadine Coyle, Nicola Roberts and Sarah Harding - recently announced their comeback plans, but Cheryl claimed once their 2013 tour was over, that would be it for the group.

However, Kimberley says she no longer thinks that way, as she made the statement in her autobiography, written before they announced they were back together.

She told the UK's Radio 1: ''I don't think we're ever going to split up now.

''I don't think any of us know what's going to happen after the tour. That's as far as we've planned for now.

''Cheryl wrote the book a long time ago. She obviously wrote it before any of the music, before we had anything in place.''

Cheryl - who has enjoyed success as a solo artist since Girls Aloud last worked together in 2009 - wrote in her book: ''We'll be working on a tour and greatest hits album. Then I think that's it for Girls Aloud.''

While Kimberley admits they won't work together constantly after the tour, she thinks they will regroup once in a while to work on new songs, tours and performances.
