Mariah Carey says Nicki Minaj threatened to shoot her on American Idol set

The ongoing feud between Nicki Minaj and Mariah Carey onAmerican Idolis far from ending soon as according to the latest report Minaj has allegedly threatened to shoot Carey.

Sources said that Mariah and Nicki had a furious fight earlier this week which led to auditions being cancelled for a day. Talking to TMZ's The View, noted journalist Barbara Walters, who spoke with Mariah, said the singer heard Nicki walking off the set, saying 'If I had a gun I would shoot the bitch." Responding to the allegation, Nicki tweeted, "I don't call TMZ n Barbara Walters cuz I stand on my own two feet. Never needed an army. God is good. Insecurity is as cruel as the grave. I guess it hurts 2 have the producers tell u to ur face that Nicki is the best judge we've had since Simon. Awww, poor u. Keep them lies cmn."

Fellow judge Keith Urban said he is neutral and he felt like "the UN". He added, "I love it, I gotta say. I love working with passionate people. I love artists. Everyone just sort of expressing themselves. It's a very alive and very invigorating work environment."
