Many of the Jersey Shore stars gathered in Atlantic City on Saturday to do what they do best: Party!
Specifically, they were on hand to help throw cast mate Jenni "JWoww" Farley a surprise party to celebrate her recent 34th birthday. The festivities began at the Italian restaurant Martorano's at Harrah's and later moved to the resort's Pool After Dark, where Jersey Shore's DJ Pauly D performed and kicked off a new DJ residency.
"I am still in shock," JWoww wrote on Instagram, alongside a slideshow of videos and photos. "I feel so special! Shout out to @illuminationpr and @djpaulyd for the ultimate surprise party & @harrahsresort #martoranosac for making it such a great night and everyone for coming ♥️."
Partygoers also included Jersey Shore co-stars Vinny Guadagnino, Deena Cortese, who attended the bash with husband Christopher Buckner, and Angelina Pivarnick, who brought along her fiancé Chris Larangeira.
"SURPRISE @jwoww !!!! I love this," Pivarnick wrote on Instagram. "I love birthdays...u deserve this mama #AC #harrahs @martotanos @steve_martorano thank u #bestfood."
She added, "What a fun night for @jwoww bday. This night goes down in the books as my favorite. Love u guys @jwoww @chris_e_piss_e @deenanicolemtv @djpaulyd #ac @harrahspoolac #lovebirthdays."
"Such a fun night with some of my best last night," Cortese wrote. "Happy Birthday J! Love you mama ! @harrahsresort @harrahspoolac #family @poolafterdark."
Also in attendance: Lauren Sorrentino, wife of cast member Mike "The Situation" Sorrentino, who in January began a prison sentence for tax evasion.
"Had the best time celebrating @jwoww last night at #MartoranosAC with this crew @Harrahsresort and @Poolafterdark," Lauren posted on Instagram.
JWoww's BFF Nicole "Snooki" Polizzi, who is pregnant with her third child, was unable to attend the party. But she was there in spirit. And, in other ways. JWoww gave her bestie a shout-out via an Instagram Story video, which her pal later reposted, writing, "LMAO I missed a good time last night.
Snooki has been supporting JWoww as she deals with a nasty divorce from husband Roger Mathews, with whom she shares two children.
