Singer Nicki Minaj threatened to punch Mariah Carey Tuesday in Charlotte, N.C. and unleashed a expletive-filled tirade, according to TMZ and the New York Daily News.
Both women are currently serving as judges for the first time this season on American Idol.
According to the reports, the fight was over a contestant's performance.
Carey reportedly called Minaj a "b---h" to which Minaj responded, "I'm gonna knock you out!"
In video posted by TMZ, fellow judge Randy Jackson can be heard urging them to "settle down."
