Deena Cortese hasn't even made her first official appearance on MTV's Jersey Shore, but she's already causing some good old fashioned drama.
In a sneak preview from the Jan. 6 return of Jersey Shore's season 2, new cast member Cortese makes her presence known in the house -- by getting in a blowout fight!
Though it's not clear what set things off, Cortese nearly comes to blows with Sammi "Sweetheart" Giancola before Jenni "JWoww" Farley steps in. The fight escalates to the point where Giancola tries to take a swing at Farley. (Watch a clip above)
As for the guys' take on what their return to Seaside will bring?
"Last summer was crazy, but now we know each other and we're going to hit Jersey hard," says Pauly D. Adds Vinny: "There will be more hookups. Jersey girls are a little easier."
Watch the preview above for more on what's in store when the cast returns to Seaside Heights -- including Snooki's July arrest and the introduction of a new contraption Pauly dubs the "grenade whistle."
New episodes of Jersey Shore premiere Jan. 6 at 10 p.m. (EST) on MTV.
