"Jersey Shore" star Nicole "Snooki" Polizzi and her fiancé Jionni LaValle welcomed a son on Sunday, August 26, in Livingston, NJ.
Lorenzo Dominic LaValle weighed 6 pounds, 5 ounces, and both mom and baby are doing well, MTV.com reports.
The new mom announced the news via her Twitter: "I am SO IN LOVE with my son Lorenzo Dominic! I had my little man last night, healthy at 6lbs! HE'S MY WORLD!"
News that the Jersey Shore star, 24, and her fiancé Jionni LaValle were expecting was officially announced in March. Polizzi revealed in May that she was having a boy.
Impending motherhood seemed to mellow the reality star, who slowed down her fast-paced lifestyle after learning she was pregnant.
"I guess [pregnancy] just made me more mature," the Snooki & JWOWW star told reporters in April. "It's different because now I'm not drinking. I'm usually partying and going to clubs, but pregnancy made me grow up a lot."
