You gotta love TMZ.com!  That site is always first on the celebrity dirt.  The stories, videos...audio recordings etc...etc.  This latest round of celeb dirt comes from the studios where "American Idol" is taped.  The show is still early in production, but it already looks like 2 of the new judges are NOT getting along. Guess who it's not.....if you said Keith Urban, you are correct.  Nicki Minaj and Mariah Carey had a "moment" during auditions in Charlotte, North Carolina on Tuesday.  According to TMZ, Nicki told Mariah that she'd knock her out!  Believe it or not, the whole ordeal came about over a disagreement regarding one contestant.  The audio is tough to make out, so I decided to transcribe

WHAT YOU MIGHT HAVE MISSED IN THE AUDIO- (Without the explitives)
Minaj- I told them I'm not putting up with her highness over there.
            - Don't lose your head....don't lose your head.  Don't tell me I'm gangster.
            - I'm not gonna sit here every minute to have you come down and harass me every minute.
Whoooooo!!
