They tried to play it down, but Nicki Minaj is comin’ for Mariah big time on the set of American Idol. Yesterday’s auditions in Charlotte had to be shut down because of the fighting between the divas. Shit is getting u-g-l-y. Nicki said “I’m gonna knock you out” and “I’m not fucking putting up with her fucking highness over there.” Do you guys think it’s for real or a stunt to get us to watch? (Photo: Pacific Coast News)

Update: TMZ has the actual video!
