Snooki is a mommi: Baby boy Lorenzo joins the party

Nicole “Snooki” Polizzi is a mom: Her baby son with fiance Jionni LaValle was born in the wee hours Sunday in New Jersey.

The “Jersey Shore” star tweeted Sunday: “I am SO IN LOVE with my son Lorenzo Dominic ! I had my little man last night, healthy at 6lbs! HE’S MY WORLD!”

Her rep added five ounces to that six pounds, giving the delivery time as a little before 3 a.m. and noting to MTV News on Sunday: “The world just got another Guido!!!”

“Lorenzo is the cutest baby I ever seen,” friend and “Snooki & J-Woww” costar Jenni “J-Woww” Farley tweeted Sunday. “Love him already.”

Snooki found out she was pregnant right after New Year’s. Her first thought when she got the news? “I’ve been drinking!” she told Us Weekly. “I was worried. It was New Year’s Eve and we were in Vegas, so I did go crazy.”

Polizzi and LaValle got engaged in March. She said in April that she did want to have a dream wedding but didn’t want to think about it or talk about it until after the baby arrived.

So let the wedding planning begin!
