Nicki Minaj went off on a rant allegedly directed at Mariah Carey during American Idol auditions Tuesday in Charlotte, North Carolina. We figured it was only a matter of time before the two divas bumped heads, but we just didn’t expect it to be so soon! Leave it to TMZ to find the video evidence of Nicki’s rant. The gossip site posted this video of Nicki letting her frustration loose on Mariah after the two singers disagreed over a contestant’s performance. Although it’s hard to make out exactly what Nicki is saying, she’s clearly infuriated. At one point, she yells, “Don’t lose your head… don’t tell me I’m a gangster.” Check out the video to see for yourself. We have a feeling this is either going to be the best or the worst season of Idol yet!
