Nicole 'Snooki' Polizzi Marks 37th Birthday with Tributes from Her Jersey Shore Costars: 'I Still Feel 25'

As Nicole “Snooki” Polizzi turned 37, her costars turned back time!

The reality star celebrated her special day on Saturday, Nov. 23, and her Jersey Shore castmates marked the milestone with some sweet throwback photos.

Polizzi kicked off her birthday festivities on her Instagram Stories on Nov. 22, sharing a photo of herself sipping a glass of red wine — along with a message of disbelief about her age.

“I can't believe I'm gonna be 37 tomorrow. THIRTY SEVEN,” she wrote. “How did I get here? I still feel 25.”

As the clock struck midnight, the star shared another post with her wine, this time a Boomerang in which she clinked the glass with the camera. “Cheers to 37,” she wrote, and added an emoji of an elderly woman.

After ringing in her birthday, Polizzi continued sharing on her Instagram Stories, reposting lots of birthday tributes, including several from her Jersey Shore costars — starting with none other than Paul “Pauly D” DelVecchio.

DelVecchio, 44, shared a grid of photos of himself and Polizzi — some old and some new — with the DJ’s iconic hair towering high and the mom of three posing with her signature duck lips.

Also celebrating Polizzi on her special day were Vinny Guadagnino and Mike “The Situation” Sorrentino. Guadagnino, 37, shared a snap of the duo on electric scooters, while Sorrentino, 42, posted a throwback shot of himself and the birthday girl, which she dubbed “iconic.”

Of course, Polizzi's BFF Jenni “JWoww” Farley also rang in the star’s special day with a post, sharing a sweet selfie of the pair.

“Everyone wish my boo @snooki a Happy birthday 🎉 👏🏻👏🏻👏🏻🍾,” Farley, 38, wrote in the caption.

Even the official Jersey Shore Instagram account got in on the action, showing the “OG party girl” some birthday love. The account shared a pic of Polizzi at the MTV VMAs earlier this year, and wrote, “Blowing kisses and sending birthday wishes to our OG party girl, @snooki 👑💗.”

As for her non-social media celebrations, Polizzi appeared to spend some quality time with her husband, Jionni LaValle, and their three kids: sons Lorenzo Dominic, 12, and Angelo James, 5, and daughter Giovanna Marie, 10.

LaValle, 37, kicked off his wife's birthday with a rose bouquet just before the clock struck midnight on Friday, Nov. 22. “Flower delivery 15 min before my bday 🥹,” Polizzi wrote alongside a photo of the flowers.

She also shared several pics and videos of her kids, including a clip of Giovanna channeling her mom’s cheer skills by dancing, lifting and flipping her younger brother Angelo in the family’s living room.

Polizzi, meanwhile, sang along to a song as she filmed, and chuckled at the little ones’ antics. She also cheered them on, yelling, “Heel stretch!” and cheering for Angelo when he obliged.
