Here's what Nicki Minaj posted on Twitter as a response:

Hey yAll. Lets just say nicki said smthn about a gun. ppl will believe it cuz she’s a black rapper. Lmao. I’ll then hit up Barbara n milk it. Ironically no camera or mic heard the gun comment tho. Lol @ the struggle. Not even the producers believed u. Say no to violence barbz.

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 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. 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…
