*First of all, on this Mariah Carey v. Nicki Minaj stuff, are they serious?

Ryan Seacrest says yes. The feuding ladies, from the opposite side of the spectrum, were caught going at it during an “Idol” tryout in Charlotte, N.C.

According to reports, the two divas were fighting over a contestant when Minaj basically announced that she’s not putting up with Mariah anymore.

Too bad for new judge Keith Urban, he was stuck in the middle of the cat fight.

On his radio show, Seacrest said “Idol” needs some passionate debate. “It did get intense,” he said. “We want that. We want them to be on this panel together. This is a good team, a great team, to go out and look for the next American Idol … the feedback that they give is very good.”

Hopefully they can make it through a full season together.

Randy Jackson and his new crew of judges make their debut in January.
