‘American Idol’ auditions in Charlotte, N.C. came to a halt as Nicki lost her cool with Mariah, swearing at and, reportedly, threatening her! Read on and watch the video for more details.

While it had been reported that new American Idol judges Mariah Carey and Nicki Minaj weren’t getting along on set, it hadn’t been proven. Until now. The two divas got into a major fight while filming auditions in Charlotte, North Carolina on Tuesday, October 2!

TMZ has exclusive video footage of Nicki, clearly enraged, yelling, “I told them, I’m not f***ing putting up with her f***ing highness over there.” They also report that, according to sources, Nicki later threatened to “knock out” Mariah, thought that was not caught on film.

The whole fight occurred right at the judge’s table, with a clearly fed-up Keith Urban stuck in the middle and Randy Jackson pacing in the background.

MouthToEars.com reports that Nicki erupted because Mariah “kept making jabs at her…called Nicki a b**** and then proceeded to cuss her out.” They also report that production was shut down for the night as a result of the incident.

TMZ reports that producers are worried about Mariah and Nicki “co-existing over the long haul.”

What do you think, HollywoodLifers? Are you surprised by Nicki and Mariah’s fight?
