'Jersey Shore' Cast -- It's GTL Time Again!

The "Jersey Shore" gang's all here -- well almost all ... as Snooki, the Situation, Deena and a once again lip-locked Ronnie & Sammi made their way back down the shore to start taping season 6 (SIX!) of the trash-tastic show.

While Jwoww, Pauly D and Vinny have yet to show their over-bronzed faces, the fist pumpers may soon be joined by a new cast member ... in the form of the unborn baby boy inside Snooki's womb.

As TMZ first reported, Snooki won't be shacking up with the rest of the boozy bunch -- or with newly sober Sitch -- while she's pregnant, opting to get a place nearby instead.
