Mariah Carey and Nicki Minaj

Mariah Carey and Nicki Minaj were the latest ladies to have a feud played out in public for everyone to witness. The two divas are on the new American Idol judging panel but they do not get along at all, so much so that auditions were cancelled after a catfight broke out between the pair.

In leaked video footage, Nicki was seen ranting that she wasn't going to put up with 'her highness over there' and shouted at show bosses to 'figure it out' before stormng off set.
