Cowell promises Girls Aloud week

Simon Cowell has promised that there will be a Girls Aloud theme week on next year's X Factor.

The 50-year-old judge made the statement on last night's Xtra Factor after a member of the public suggested the theme in a phonecall to the show.

"We always try to give the public good songs, so we suggest a group that have had a lot of hits, so in three or four years, I guarantee that we will have a Girls Aloud night," he said.

After being pressed on the subject by the caller, he added: "How's this, if we are back next year, we'll have a Girls Aloud night."

When host Holly Willoughby asked if that was a promise, Cowell nodded in agreement.

The X Factor semi-final airs next Saturday at 8pm on ITV.
