Mariah Carey just made it clear -- TMZ was dead on when we reported Nicki Minaj threatened to shoot her.

Barbara Walters reported on "The View" today she spoke with Mariah, who said she was concerned because "Nicki walked off the set and multiple people heard Nicki say, 'If I had a gun I would shoot the bitch.'"

Walters says Mariah told her, for safe measure, she's hired extra security.

And, Walters adds, Mariah said Nicki has not apologized but told her she loves her ....HOWEVER, Nicki said they might be fighting again on "American Idol."



For her part, Nicki just 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."

Minaj continued, "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."

So much for the truce.
