Nicole "Snooki" Polizzi gave birth to a baby boy shortly before 3 a.m. Sunday, at Saint Barnabas Medical Center in Livingston, N.J.
"The world just got another Guido!!! Lorenzo Dominic LaValle has entered the world weighing 6 lbs, 5 oz. Nicole, Jionni & Enzo are doing great!" reports MTV.
On Sunday, she Tweeted about how much she is already enjoying parenthood. "Being a mom is an amazing feeling!!! I love my little man to death! Jionni is such a cute dad," she wrote. "I am SO IN LOVE with my son Lorenzo Dominic."
The new mom went into labor Saturday night.
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."
Luckily for the baby, he already has a built-in family aside from his natural one. Fellow TV cast mate Paul "Pauly D" DelVecchio told PEOPLE in July, "I want to be 'Uncle Pauly,' and I want to be a part of that baby's life, because Snooki is one of my best friends."
In June, Snooki confessed to PEOPLE that she'd been afraid to tell her father she was pregnant, but once she broke the news, her family was thrilled.
"[My dad] is excited now. I think [my parents] are more excited than we are," she said at the time. "I'm their only child and this is going to be their [first] grandchild."
