When Mariah Carey and Nicki Minaj fiercly argued during an American Idol audition in North Carolina, Mariah felt extremely uncomfortable.  In an interview with Barbara Walters, Mariah recalls the event:

"It felt like an unsafe work environment.  Anytime anybody's reeling threats at somebody, you know, it's not appropriate. I'm a professional. I'm not used to that type of environment."

Carey claims that the war of words was worse once the cameras were turned off.  Mariah remembers Minaj saying, "If I had a gun, I would shoot that b!tch."  Because of the blow-up, Carey hired more security.

Minaj denies mentioning anything about a gun.
