Mariah Carey has slammed Nicki Minaj.

The 43-year-old singer - who repeatedly clashed with the "Starships" hitmaker when they were both judges on American Idol last year - insisted she wants to press "delete" on her time on the show and claimed she can't even remember her fellow panelist. When asked about the program on Power 105.1's "Breakfast Club" radio show, she said, "I was a professional on that show, and that's all I have to say. I was a complete professional."

When one of the hosts said, "Nicki was late though," Mariah replied "Who?" She added, "I don't even remember what that was. That was a moment in my life that I'm just going to press delete."

The "You're Mine (Eternal)" singer - who has twins Moroccan and Monroe, two, with husband Nick Cannon - previously admitted she "hated" being on American Idol, suggesting Nicki was the reason she had such a bad time on the show: "Honestly, I hated it. Here's what it was. I was the first person who signed on...I thought it was going to be a three-person panel. They gave me a nice... monetary moment, and I was just like, 'OK, Randy Jackson will be there; I've known him forever. He used to play bass for me. Like, this isn't a big deal. This will be nothing.' But it wasn't that. It was like going to work every day in hell with Satan."
