(LOS ANGELES) -- Mariah Carey and Nicki Minaj have downplayed rumors that they haven't been getting along on the American Idol set. But TMZ.com has posted video that strongly suggests the two aren't exactly the best of friends.
The video, shot during Idol auditions in Charlotte, N.C., on Tuesday, depicts an irate Minaj bickering with Carey.
Minaj is seen complaining, "I told them, I'm not f***in' putting up with her f***in' highness over there."
According to TMZ, there was another moment not captured on tape when Minaj threatened to "knock out" Carey.
The website MouthtoEars.com is reporting that Minaj walked off the set because Carey "kept making jabs at her" and cursing at her. Things got so out of hand that producers ended auditions for the day, according to MouthtoEars.com.
TMZ says the war of words stemmed from a disagreement over a contestant's performance.
Carey on Tuesday evening tweeted, "whyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyy," but it's unclear if she was referring to the incident.
