When Jennifer Lopez and Steven Tyler decided to leave American Idol after last year, many fans grumbled that they would be hard to replace.  Bringing on Mariah Carey and Nicki Minaj as replacements didn’t seem to sit too well with the fans either, and adding Country star Keith Urban hasn’t done much to calm the fear of the fans that there may be too many egos on the show now to make it work.

Now comes word that there has already been a major blow up during taping this week.  TMZ Cameras happened to catch the “argument” between Mariah and Nicki…who have been rumored to not like each other very much.

Producers of the show reportedly had to suspend auditions long enough to get the two settled down.
