The final season of Jersey Shore
is quickly approaching, but that doesn't mean the party's over just yet!
Paul "Pauly D" DelVecchio
, Mike "The Situation" Sorrentino
and Ronnie Ortiz-Magro
spent a night out at Bootsy Bellows in West Hollywood on Tuesday.
Wearing their signature T-shirts, the cast mates arrived around 11:30 p.m. but didn't spend too much time together.
Nestled in a VIP room, "Ronnie spent a lot of time texting and on his phone while Mike was laid back and relaxed," an onlooker tells PEOPLE. "Pauly was the most social chatting with a lot of people."
Around 12:15 p.m. Pauly left the VIP room to say hello to Paris Hilton.
While there was no fist-pumping to be seen, that didn't stop the Jersey Shore
stars from staying until the club closed.
