According to TMZ:
Nicki Minaj caused a stir at the “American Idol” auditions in Charlotte, today, after cussing Mariah Carey out.
In the footage, Nicki is clearly yelling, “I told them, I’m not f*ckin’ putting up with her f*ckin’ highness over there.”
Sources are saying Nicki later threatened to “knock out” Mariah, which wasn’t caught on tape.
The disagreement supposedly went down over a contestant’s performance.
