Nicki Minaj has been caught cussing at Mariah Carey on American Idol. It was never going to be long before the two divas came to blows but we thought Carey would be the first to lose her cool. Apparently not! TMZ have posted footage of Nicki Minaj ranting at American Idol’s production staff and at Mariah herself. The footage is a little blurry and TMZ had to bleep out quite a large portion of what was coming out of Nicki’s mouth. You can see Keith Urban sat between Nicki and Mariah looking exasperated and Randy Jackson is stood at the end of the table, equally powerless.

Not all of the rant is audible but you can hear Nicki saying “I told them I'm not f**kin' putting up with her f**king highness over there. Figure it the f**k out. Figure it out… I'm not gonna sit here every f**king minute to have you come down and harass me every minute everyday.” According to the report, Nicki also threatened to “knock out” Mariah but said it before the camera was recording.

It’s hard to know what the American Idol bosses will be thinking about this latest drama between Nicki and Mariah. In essence, it will probably be good for the show as it’s bound to get more and more viewers intrigued and tuning in. After all, one of the main reasons they revamped the judging line-up was too boost falling viewer figures. What better than a foul-mouthed rant from a rapper in a pink wig to do that?
