Balloons and babies? That's not how the Jersey Shore gang used to party.
On the season 2 finale of MTV's Snooki & JWoww, new mom Nicole "Snooki" Polizzi is in high gear prepping a surprise engagement party for her costar and son's godmother, Jenni "JWoww" Farley, and her fiancé, Roger Mathews.
With baby Lorenzo in tow, a recently slimmed-down Polizzi is putting up decorations before her guests of honor arrive, when longtime pal Pauly D shows up.
"Look at this little Guido," DelVecchio says, grinning from ear to ear with amazement when he sees tiny Lorenzo for the first time. "He is amazing."
Polizzi refers to DelVecchio as "Uncle Pauly," who seems to take the title seriously. "I gotta give him a blow out," he says. "You did good Snooks! You did good!"
As more guests arrive, Lorenzo grabs their attention. "He looks so much different," say pal Sammi Giancola, who walks in with boyfriend Ronnie Ortiz-Magro. "His head's bigger."
The show airs Tuesday (10 p.m. ET) on MTV.
