*Now that British pop star Cheryl Cole is out at Simon Cowell’s forthcoming U.S. version of “X Factor,” there are reports today that Mariah Carey is back in the mix – but not as a judge, as had been rumored last spring before Cole became involved.

According to WENN, Carey will join the reality show as a mentor – much like Simon Cowell’s ex-girlfriend Sinitta is on the UK version.

Although nothing has been officially announced or confirmed, the news has reportedly stunned Sinitta, who has worked on the UK version for the last seven years and was expecting to get the same gig in America.

“Well, let’s just say feathers will fly if Mariah takes my spot,” Sinitta told Britain’s Daily Star newspaper. “Although she is a mega diva vocally, you can expect another XF USA drama. I won’t just roll over and take it. I hope she can run in high heels.”

Mariah is set to join Cowell for the “judges home” stage of the competition, where potential finalists are invited to their mentor’s luxury pads to perform a song of their choosing.

Last April, the then-pregnant Carey was rumored to be considering a judging role on the “X Factor” but L.A Reid, Nicole Scherzinger and Paula Abdul have already begun work on the show.
