Snooki has welcomed her first child into the world.

The Jersey Shore star – real name Nicole Polizzi – welcomed 6lb 5oz son Lorenzo Dominic LaValle at Saint Barnabas Medical Center in New Jersey on Sunday morning.

A representative for the star told MTV: “The world just got another Guido! Lorenzo Dominic LaValle has entered into the world weighting 6lbs, 5oz. Nicole, Jionni & Enzo are doing great.”

MTV – which hosts Jersey Shore - added their congratulations, saying they could not wait to see the little boy on the show.

They said: “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.”

Snooki – who is renowned on the show for her drunken antics - found out she was going to have a boy before she gave birth, but revealed she was secretly hoping to have had a girl.

She said: “As long as it’s healthy, I’m fine. So if you’re a boy, I’ll still love you, obviously!”
