Nicki Minaj vs. Mariah Carey: 'Idol' Smackdown Caught on Tape

Singers Nicki Minaj and Mariah Carey got into a verbal battle royale at the "American Idol" auditions in Charlotte, North Carolina on Tuesday. In a video obtained by TMZ, Nicki hurls threats and obscenities at Mariah.

Among the “Pink Friday” singer's choice words…“I'm gonna knock you out” and “I'm not f**kin' putting up with her f**kin' highness over there.”

TMZ also said the argument escalated off camera. Nicki supposedly yelled, "If I had a gun I would shoot her," but producer Nigel Lythgoe told the press that the death threat never happened. "The statement [that Nicki made a death threat] is absolute rubbish. It's absolutely not true in any way, shape or form," he said.

According to Splash, Mariah started the fight by calling Nicki a “b**ch,” causing the younger singer to storm off. When producers finally convinced Minaj to return, Carey continued hurling insults, causing the 29-year-old to attack.
