Nicki Minaj and Mariah Carey caught in taped tiff

(CNN) -- We've heard plenty about the rumored feud between new "American Idol" judges Nicki Minaj and Mariah Carey, but now TMZ appears to have captured some evidence.

The website's obtained video of "Idol's" Tuesday auditions in Charlotte, North Carolina, which were reportedly interrupted when Minaj blew up at Carey at the judges' table.

It's hard to hear exactly what Minaj is saying in the clip, but TMZ reports that at one point Minaj can be heard saying, "I told them I'm not f****n' putting up with her highness over there ... Figure it the f*** out."

The site reports that the disagreement happened over a contestant's performance, with "Idol's" third new judge, Keith Urban, stuck in the middle.

Gossip of a feud between Carey and Minaj surfaced before the colorful rapper even officially signed on to "Idol," and the two gave an attempt to squash the rumors at a press conference in September.

"We're getting along wonderfully, darling," Minaj told press at the time, while Carey joked that a feud wasn't possible because they simply hadn't had enough time to stir one up.

"How are we going to feud in two days?!" she said with a laugh. "Like, a feud takes a little longer to ... you know, spread out."

Fox had no comment on the video, and CNN has yet to hear back from representatives for Minaj or Carey.
