The Jersey Shore cast's boozy Seaside Heights nights may be long behind them, but over half of them reunited this past weekend to prove they can still party and fist pump like champs in honor of Sammi "Sweetheart" Giancola's birthday.

Sammi celebrated turning the big 3-0 at New York City restaurant Beautique, and among those in attendance were Snooki (aka Nicole Polizzi), Jenni "JWoww" Farley, Vinny Guadagnino and Deena Cortese. Cortese, you may remember, replaced cast member Angelina after Season 2.

JWoww and Snooki might be moms now, but they managed to get crazy, get wild with their former housemates, or at least throw back a martini or two.

Deeming herself a "#lightweight" nowadays, Farley captioned one photo, "Martini is down and I am drunk." The ladies wore their finest metallics, and later danced to Drake's "Once Dance" without tossing a drink in anyone's face or finding a corner to argue in. The gang has truly grown up!

Vinny, seen here with JWoww's husband, currently sports some sculpted facial hair — though if you're a fan of Vinny and Ma, the Cooking Channel show he evidently cohosts with his mother, you knew that already.

JWoww still seems pretty fun.

Deena, who got engaged to boyfriend Christopher Buckner in November 2016, struck a pose with fellow "meatball" Nicole. Meanwhile, Sammi's on-again-off-again Jersey Shore boyfriend, Ronnie Ortiz-Magro, seemed to be nowhere in sight.
