Before they became “celebrities,” Jersey Shore cast members like Snooki, Pauly D and The Situation could never, EVER get into Manhattan’s finest clubs because, let’s face it, they are guido cheesedicks of staggering proportions and the doormen at places like Avenue and 1Oak and Greenhouse get paid well to keep people like them on the outside. Not that it mattered any, since the cast members of Jersey Shore were probably content to party exclusively at places populated by their guido brethren, but now that they’re sort of famous, these freaks are now able to get into places they couldn’t get into before and, naturally, trouble has already ensued.

Reports the Daily News:

A few of the show’s finest, including Nicole (Snooki) Polizzi, Pauly D, Mike (The Situation) Sorrentino and Vinny Guadagnino, infiltrated downtown hot spot Greenhouse on Monday night, and at least one regular wasn’t too happy about it. In fact, the female partygoer almost got into an altercation with pint-size Nicole, who was making her way to VIP seating, simply because she knocked off one of her accessories.

“If jenniwoww was here when the broad knocked my hat off my head youd be knocked out,” she tweeted a moment later, referring to her ultra-aggressive sidekick on the show, Jenni (J-WOWW) Farley.

Luckily, J-WOWW was nowhere to be found or there surely would have been a brawl – possibly over nothing.

“It looked like the girl was reaching to touch Pauly D,” one partygoer notes, adding that Snooki didn’t look too happy about the girl accidentally messing with her “poof.”

Added another female reveler: “They all walked in like they owned the place. And Snooki completely overreacted.”

This is going to get ugly real fast.
