“Jersey Shore” star Nicole “Snooki” Polizzi is officially a mom.

Polizzi gave birth to a baby boy, Lorenzo Dominic LaValle, just before 3 a.m. Sunday with fiance Jionni LaValle by her side, according to MTV.

Little Lorenzo weighed in at 6 pounds, 5 ounces. He was born at Saint Barnabas Medical Center in Livingston, N.J., according to MTV.

"The world just got another Guido!!!” a representative for Polizzi told MTV. “Nicole, Jionni & Enzo are doing great!"

MTV was also excited for its reality star, saying in a statement: "We couldn't be happier for Nicole and Jionni on the healthy delivery of their baby boy! We look forward to Lorenzo's first trip to the Jersey Shore and can't wait to see his first animal print onesie."

Fans will get to share in the reality star’s experience with pregnancy this fall. MTV says the new season of “Jersey Shore” will feature stories from the last part of Polizzi’s pregnancy when the show returns in October.
