(TMZ) - Nicki Minaj derailed the "American  Idol" auditions in Charlotte, North Carolina Tuesday, after swearing at Mariah  Carey and threatening, "I'm gonna knock you out"... sources tell  TMZ.

In the footage, obtained by TMZ, Nicki is clearly furious, shouting, "I told them I'm not f*****' putting up with her f*****' highness over  there."

Sources say Nicki later threatened to "knock out" Mariah, but  she said it before the video starts.

It all went down while the two were sitting at the judge's table, with Keith Urban sitting in  between them and Randy Jackson sitting on the far end, next to Mariah.

TMZ reports the whole thing exploded over a disagreement over  a contestant's performance.

Listen closely as you play the video...  you'll hear:

Nicki  Get this s**t in self  control.  Get in control.  Get in control. 
Randy  Settle down, settle down
Nicki  Don't lose your head.  Don't lose your head  (inaudible).  Don't tell me I'm a gangster.
Nicki (inaudible) every 5 minutes.  So every time you patronize me, I'm-ma take it back, and if you've got a f****** problem,  handle it.
Nicki I told them I'm not f*****' putting  up with her f****** highness over there.  Figure it the f*** out.  Figure it out.
Nicki I'm not gonna sit here every  f****** minute to have you come down and harass me every minute everyday.

Mariah is talking back at Nicki but it's hard to hear what she's  saying.

According to MouthToEars.com, producers ended the  auditions for the day so the two judges could cool down.  We've confirmed  that happened.

Big wigs on the show seem uncharacteristically upset by the blow up.  It seems producers are worried about Mariah and Nicki  co-existing for the long haul.
