This is not OK.
Looks like this feud is real after all!
Insiders, who were in the room when the fight went down, say Nicki was screaming at Mariah:
"I'm gonna knock you out!"
Then shouted at producers:
"I told them, I'm not f*ckin' putting up with her f*ckin' highness over there."
Why were they fighting??
Apparently this whole thing started because they disagreed about a contestant's performance.
OoOoh, that's right! This all went down while they were sitting at the judges table!
We don't know how the contestant reacted to this verbal battle, but we hear Keith Urban — who was sitting in between the lady judges — was pretty shaken!
And he's not the only one — producers are scared out their mind that one of the judges is gonna quit… or worse!
We're praying this is a stunt, but we wouldn't be surprised if this fight is 100 percent authentic. Two divas in one room is NOT a good combo!
