Jerzdays are coming back again.

"Jersey Shore Family Vacation" was so lit that "Jersey Shore Family Vacation Part 2" is on its way.  After all, as Vinny Guadagnino says, "Why not keep the love fest going?" This time, the crew is headed to Sin City for the wedding of Paul "Pauly D" Delvecchio, as we see in MTV's official trailer.

In addition to Guadagnino and Delvacchio, we see the return of Nicole "Snooki" Polizzi, Mike "The Situation" Sorrentino, Jenni "JWoww" Farley, Deena Nicole Cortese, and Ronnie Ortiz-Magro. Original "Jersey Shore" cast member Samantha "Sammi Sweetheart" Giancola has again skipped the reunion.

Some of the drama in the trailer involves who gets to go to Las Vegas. The preview shows that Angelina Pivarnick want to join, but the rest of the gang isn't necessarily on board. And that's just the beginning. There's a pregnancy announcement, nudity, and, of course, lots of partying in Sin City.

Watch the trailer below.

"Jersey Shore Family Vacation Part 2" premieres Aug. 23 at 8 p.m. ET/PT on MTV.
