Oh, Snap! Mariah Carey on Nicki Minaj: “I Didn’t Know She Sang”

Season 12 of American Idol hasn’t even started yet, but the show’s getting more and more heated as the feud between Mariah Carey and Nicki Minaj continues.

The two new judges on Fox’s singing competition developed serious beef while filming the series, but on Nightline Monday night Carey said it’s squashed. Barbara Walters pressed the subject by reading lyrics from Minaj's new song, which is reportedly about the show.

"I'll take it. Sign on the dotted line ... but I'm quick to a check a bitch if she's out of line" Walters read before asking, "Are you the bitch she's singing about?"

"Don't know,” Carey answered. “I didn't know she sang. I thought she rapped. Or whatever."

Hmmm. Sounds like beef to us.

American Idol with Mariah Carey and Nicki Minaj premieres on Wednesday, January 16 at 8 p.m. EST on Fox.
