Girlfight! Mariah Carey and Nicki Minaj Already at War on “American Idol”

Here’s an incentive to tune into the upcoming 12th season of American Idol. And we aren’t doing about Nicki Minaj’s colorful assortment of hair extensions.

It’s only been two days, but the newly-minted talent show pundit and her diva counterpart, Mariah Carey, are reportedly “already at each other’s throats.”

Now this is what we call “Must See TV!” But we can’t help but feel sorry for Keith Urban. After all, the poor guy has to sit between them!

Mariah, who signed on thinking she would be the only lady on the panel, isn’t pleased about the last-minute addition of the outre femcee. Mariah is rumored to have hung up on Idol producers when they called to let her know she’d be sharing the spotlight with Nicki.

The music heavyweights — who collaborated on Mariah’s 2009 single “Up Out My Face” — wasted no time asserting their dominance at the show’s first round of auditions in New York City over the weekend. During filming, Carey allegedly took to frequently interrupting Nicki during her critiques.

And rudeness makes Minaj a very unhappy girl; she retaliated by talking over Mariah.

Real mature, girls.

“These girls just don’t like each other,” an Idol spy told TMZ.

When asked about their rumored feud, Mariah laughed it off, telling The New York Daily News:

“There’s been a feud in two days? A feud takes a little longer.”

When asked the same question, Nicki “simply mumbled something inaudible.”

Awkward!

The new season of American Idol premieres in January.
