Another A-list star just joined X-Factor.
"I think Mariah will have a role on the live shows," Cowell told Spokane, Washington disc jockey Brown Friday on her 92.9ZZU radio show. "I met her recently and she was on great form."
Simon kept the details of her role a secret, but he joked that Mariah had a great idea about she could be involved.
"Her idea was to be the judge of the judges, which only Mariah could come up with," Cowell told Brown. "She'll be involved in some form. I literally adore her. I love her to bits."
That's so something Mariah would say. We already know L.A. Reid and Cheryl Cole are confirmed as guests, and Nicole Scherzinger is in talks to host the show, but that's all we know so far.
Additional judges and the show two hosts will be announced at a later date. So would you love to see fill the last judges seat?
