With only two weeks of American Idol auditions in the books, Nicki Minaj and her pink hair went ballistic on Mariah Carey!  What was once a disagreement, turned out to be a scene from an episode of Jerry Springer....

I'm sorry, but I still can't get over that hair!!!  Never mind the trailer park "verbiage" that is taking place in this video.

According to TMZ, Minaj says, "Don't lose your head. Don't lose your head ... Don't tell me I'm a gangster," and, "I'm not going to take it back, and if you've got a f---ing problem, handle it.  I told them,I'm not f–––in' putting up with her f–––ing highness over there. Figure it the f––– out."

Mariah then responds to Nicki, "Ohhhhh, why, why, why?"

OH---and how many people saw this coming?  You don't have to watch or be a fan of American Idol to know this was going to happen.  I can't help but applaud the producers who thought pairing up these two was a great idea.

Nicki also told Mariah that she was "boring as f*ck" and allegedly threatened to knock Mariah out -- but that part wasn't shown on the tape.  Apparently, the drama escalated to the point that producers had to shut down production so that Nicki and Mariah could cool. off.

It should be noted that Niki has now got into confrontations with Cher, Lil Kim, and now Mariah....what do these three have in common? They're all GRAMMY winners!
