Lorenzo Dominic LaValle was born at approximately 3 a.m. on Aug. 26 at Saint Barnabas Medical Center in Livingston, N.J. He is the first child for both Polizzi, 24, and her fiancée, Jionni LaValle, 25. "The world just got another Guido!!! Lorenzo Dominic LaValle has entered the world weighing 6 pounds, 5 ounces. Nicole, Jionni & Enzo are doing great," her rep told the site.
Polizzi also took to Twitter early Sunday to gush about the new man in her life, writing, "I am SO IN LOVE with my son Lorenzo Dominic ! I had my little man last night, healthy at 6lbs! HE'S MY WORLD!"
Polizzi announced she was engaged and expecting back in March. Her pregnancy was first documented on Snooki & JWoww, and it will also be seen on the next season of Jersey Shore, which premieres on Thursday, Oct. 4. In the new season, Polizzi moved out of the cast's famed Seaside Heights beach house into her own place nearby.
Snooki & JWoww was also recently renewed for a Season 2.
