Just how bad did things get during Nicki Minaj and Mariah Carey's spat on the set of American Idol? Nicki allegedly threatened to shoot the 42-year-old singer. Carey shared details about the fight with Barbara Walters, and has reportedly beefed up security in the wake of the threat.

"She said that when Nicki walked off the set, multiple people heard Nicki say, ‘If I had a gun I would shoot the bitch,’” Barbara Walters explained on The View. “She said she’s very concerned. She is with her twins. She doesn’t feel that anything would happen, but Nicki is unpredictable, and Mariah says she can’t take a chance and she has hired extra security.”
