Drops the N-Bomb
The foul-mouthed female is Deena Nicole Cortese -- the same chick who sucked down a beer bong with Snooki in Seaside Heights this weekend.
Turns out Deena recorded a video blog on her MySpace page back in 2008 -- in which she rants about the way she's been treated by some dudes ... swears revenge ... and then says to the camera, "We're gonna play you out, n**ga."
Sources close to production confirm Deena will be appearing in a number of episodes during the third season of "Jersey" ... but she isn't considered a "permanent" cast member.
MTV had no comment on the N-bomb situation.
