Nicki Minaj insults Mariah Carey During 'American Idol' Audition

This sooooooo crazy. A big fight happened between Nicki Minaj and  Mariah Caeey during American Idol's audition over the performance of a contestant.
Nicki started swearing so they had to round up the audition for the day but Mariah Carey was so calm in her response (just like a diva).
Did Nicki forget that the audition was been recorded?
