 Over the weekend the new American Idol judges were revealed and while Mariah had hoped she will be the only Diva on the judges table, Producers had to add Nicki Minaj to the line up and now Mariah is feeling Upstaged.

Anyways Mariah Carey wasted no time proving what everyone thought of her, there's only room for one diva on "American Idol."


Carey and Nicki Minaj went at it during the first "A.I." taping Sunday in NYC. When Nicki started critiquing a contestant, Mariah would interrupt, not once, but many times and Each time Mariah interrupted, Nicki fought back by loudly talking over Mariah.

One "A.I." spy said Mariah and Nicki tried to cover their disdain for each other but everyone saw through it, adding, "These girls just don't like each other."

You may recall that when producers called Mariah to tell her that Nicki would probably be joining her as a judge she reportedly hung up the phone.
