It looks like the rivalry between these two American Idol judges won’t be ending any time soon after both Mariah Carey and Nicki Minaj released the music videos to their new songs yesterday.

Being the diva that she is, the We Belong Together singer didn’t hold her tongue when it came to slamming the 31-year-old rapper.

On Power 105.1’s Breakfast Club radio show, the singer, who was promoting her new song You’re Mine (Eternal) pretended she never heard of Nicki Minaj – as if!

“I don’t even remember what that was. That was a moment in my life that I’m just going to press delete,” she said.

Neither Mariah nor Nicki have been invited back to the judging panel of American Idol, but that doesn’t mean the war ends here.

Don’t you just love a good celebrity feud?
