NICKI MINAJ CUSSED OUT MARIAH

Battle of the divas just went into over drive. recently Nicki Minaj shocked peeps during the "American Idol" auditions in Charlotte, North Carolina Tuesday, after cursing at Mariah Carey and threatening, "I'm gonna knock you out" ... but Mariah FIRED RIGHT BACK. 

In the footage shot by TMZ, Nicki is obviously raging mad ... shouting, "I told them I'm not f*ckin' putting up with her f**kin' highness over there."

Mariah can be heard saying, "“Oh why, WHYYYY .do I have a three year old sitting around me?”

Carey continues, "I can’t see my kids, because you decided to act like a little crazy bitch and go all around the stage.”

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.
We're told the whole thing exploded over a disagreement over a contestant'sperformance.

Here is the conversation:Nicki: Think I'm playin? Think this sh*t is a f*cking joke? Think it’s a joke? Think it’s a joke? Think it’s a joke? Say one more disrespectful thing to me, if you say one more disrespectful thing to me -- off with your head!Mariah: I am not being disrespectful.
