While we’ve heard a lot about what went down between Nicki Minaj and Mariah Carey during last week’s American Idol auditions in Charlotte, North Carolina, the real reason for Nicki’s explosive curse-filled rant has remained unclear.

But according to People, tension between the two reached a fever pitch last week because Mariah made it clear she doesn’t think Nicki is qualified to judge Idol.

"Mariah has been saying little things to jab at Nicki from day one of shooting," an insider said. "Mariah doesn't think Nicki can sing and doesn't think she should be judging folks. Nicki has been taking all of the jabs, but on this particular day she lost it."

Reportedly, tempers flared when an opera-loving singer came in to try out for the show, and Mariah (whose mother is an opera singer), carried on her conversation with the contestant a little too long for Nicki’s liking.

“Mariah was talking to her as a pop singer who also liked opera ... Nicki cut her off and slammed her fist on the table. Mariah may have been going on a bit too long but she did apologize. But then Nicki flipped out and started yelling,” the source stated.

Nicki’s rage-out, of course, was caught on tape. According to the source, it could’ve only been a select few people who leaked the footage.

“On the day of the fight production staff were the only people in the room,” an insider explained, claiming that showrunners are talking about cutting Nicki loose. “That is still up for debate,” the source said. “They are worried about how she will act during the live shows.”

The producers themselves released a statement to the contrary on Friday, saying “We love and support all of the judges and the fantastic work they are doing, and we can't imagine a better group to find the next American Idol.”
