Snooki was taken to St. Barnabas Medical Centre in Livingston, New Jersey in the early hours and gave birth to a baby boy shortly afterwards. Her fiancé Jionni LaValle was understood to have been at her bedside and the couple have named their son Lorenzo Dominic LaValle, reports MTV.
Earlier, a spokesperson for the reality star released a statement asking for fans to respect the pair's privacy, reassuring them that they will "get to meet her Italian Stallion newborn soon enough".
They later announced that the 24-year-old had given birth in true Jersey Shore style.
"The world just got another Guido!!! Lorenzo LaValle has entered the world weighing 6lbs 5oz. Nicole, Jionni & Enzo are doing great!"
Snooki took to Twitter before entering hospital, but chose not to mention the developing situation. Instead, she simply tweeted the word "Fierce" accompanied by a picture of three big cats.
