It’s only been two weeks and there are already sparks flying on the judges’ panel at “American Idol.” TMZ has obtained video of Nicki Minaj lashing out at fellow judge Mariah Carey during auditions in Charlotte, North Carolina.

After disagreeing over a contestant’s performance, Nicki loses her cool, shouting, “I told them, I’m not f*ckin’ putting up with her f*ckin’ highness over there.” Sources tell TMZ that she also threatened to “knock out” Mariah.

Producers ended the auditions early so the two judges could cool off. They are reportedly worried that this could have longterm effects on the show.

When asked about a feud last month, Mariah just laughed. “How are we gonna feud in two days? Let the feud take a little longer to spread out,” she said.
