Remember those rumors of a feud between Nicki Minaj and Mariah Carey on the 'American Idol' judging panel? Both ladies denied any drama, but it looks like they may have been lying. New video has emerged of Minaj flipping out at Mimi, and though both the women are gorgeous, this footage ain't pretty.

At 'Idol' auditions in Charlotte, N.C. today (Oct. 2), Minaj and Carey got into an argument over a contestant's performance. Minaj, seated at the far left of the panel, and Carey were separated by Keith Urban, who was seated between the dueling divas. It's a little hard to make out what everyone is saying in the clip because of the background noise and bleeping, but you can hear Minaj yell, "If you got a problem, handle it! ... I told them, I'm not f---in' putting up with her f---in' highness over there." Yikes!

TMZ reports that Minaj also threatened Carey, saying, "I'm gonna knock you out!" However, that wasn't caught on video. It's difficult to hear what Carey says back to Minaj in the video, but she's clearly doing her diva moan and saying "Why? Why? Whyyyyy?" You can also clearly see her pointing at the Harajuku Barbie. Carey even tweeted (that was later taken down), about the incident, subtly writing: "whyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyy."

Another source reports that Carey kept making disparaging remarks at Minaj, who eventually had enough and flipped out. TMZ noted that producers are pretty shaken up about the blowup and stopped filming for the rest of the day so that the two beefin' babes could cool off.

Here's hoping the ladies can settle their differences, because we adore them both! Maybe they need to re-listen to 'Up Out My Face' and remember the better times.
