Snooki has given birth!

The Jersey Shore star and her fiance Jionni LaValle welcomed their first son at 3 a.m. on Sunday morning (August 26), a rep for Snooki confirms to Wetpaint Entertainment.

“The world just got another Guido,” Snooki’s rep told us. “Lorenzo Dominic LaValle has entered the world weighing 6lbs, 5oz. Nicole, Jionni & Enzo are doing great!”

Snooki went into labor during Saturday afternoon and checked into St. Barnabas Hospital in Livingston, NJ.

The reality star has been dating Jionni since 2010, when she met the New Jersey native while filming Jersey Shore Season 3 in Seaside Heights, NJ. The pair hit it off at a club after Jionni and his family came to “rescue” his female cousin from the Jersey Shore boys after she went over to their home after a night of partying. The couple became serious shortly after Season 3 wrapped filming.

The duo announced that they were expecting their first child back in March. Jionni proposed to Snooki on Valentine’s Day of this year.

The star has already been sharing her excitement about being a new mom on Twitter. “I am SO IN LOVE with my son Lorenzo Dominic,” Snooki tweeted. “Being a mom is an amazing feeling!!! I love my little man to death! Jionni is such a cute dad.”

Congratulations to the happy couple!
