American Idol producers were forced to cancel auditions in Charlotte, North Carolina on Tuesday after Nicki Minaj and Mariah Carey got into a fierce verbal disagreement. Fellow judges Randy Jackson and Keith Urban were stuck in the middle of the blow up, where Nicki said she was sick of her co-star's '"f*****g highness."
In video footage obtained by TMZ, Nicki can be heard cursing at Mariah while the "Butterfly" songstress wails "Why? Why?"
Sources revealed to TMZ that Nicki later told Mariah "I'm going to knock you out," which was not caught on camera.
