The Nicki Minaj-Mariah Carey drama continues, and it seems like the producers of American Idol will have their hands full this season, as Nicki Minaj promises the feud isn't over.

We reported on the first incident, when Nicki Minaj was caught on tape yelling at Mariah, and she also allegedly threatened to knock Mariah out (which wasn't caught on tape). 

Mariah Carey then talked to Barbara Walters and told her that Nicki had threatened to shoot her, as TMZ reports. Walters, who appeared on The View, said that Mariah was concerned because, allegedly, "Nicki walked off the set and multiple people heard Nicki say, 'If I had a gun I would shoot the bitch.'"

Nicki has taken to Twitter to talk about the situation. She tweeted in regards to Barbara Walters, "Barbara walters didn't reach out from our team barbz. I guess we're too dangerous. Don't shake if u don't wannA get shook!!!! LmAooooooooooo. 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." She continues, "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."

Nicki's Twitter rant continued, "I thought we resolved it yesterday but I see u want ur pity party to continue. So I'm bout to po dot tea... All I do is compliment u. That's not enuff? Ur a legend, cheer up. U don't have to run down ur resume or feel intimidated. Shady McGrady..."
