Simon Cowell confirmed that Mariah Carey will take part in the American version of 'X Factor' this fall -- but won't be sitting at the judge's table.

UsMagazine.com reports that Cowell dished on his new, already-buzzed-about show in a Spokane, Wash., radio interview on 92.9ZZU.

"I think Mariah will have a role on the live shows," Cowell told radio host Jackie Brown. "I met her recently and she was on great form."

Carey will have her hands full in just a month when she gives birth to twins, making her unable to join Cowell and L.A. Reid as a judge in September. However, Cowell insists the singer will still have a part in 'X Factor.'
