'American Idol' judges Mariah Carey, Nicki Minaj already not getting along?

Mariah Carey and Nicki Minaj are already going head-to-head for the diva crown on the new season of "American Idol," according to TMZ.com.

Apparently, during the first "A.I." taping, Minaj could barely get a word in, as Carey continued to interrupt her critiques, eventually resulting in the two women trying to talk over one another.

According to TMZ, when the producers originally informed Carey that Minaj would be a new judge on the show, she hung up the phone on them.

The divas will be joined by country star Keith Urban and stalwart Randy Jackson on the judging panel for season 12.
