From what we've been hearing, NICKI MINAJ and MARIAH CAREY haven't exactly been BUDDIES on the set of "American Idol"...but Nicki doesn't seem to hold any personal grudges.

In an interview with E! News, Nicki said that she'd be up for performing alongside Mariah on "Idol". She said, quote, "I would do that. I think people would be interested in seeing that."

(--From allegedly threatening to SHOOT her to performing onstage with her? This is kind of like TUPAC and BIGGIE in reverse.)
