No need to formally congratulate them: an enthusiastic fist pump should do the trick.
Nicole "Snooki" Polizzi and her love of two years, Jionni LaValle, welcomed their first child together Sunday in Livingston, NJ, a son named Lorenzo, a rep for the pint-size star tells Us Weekly.
“The world just got another Guido!!! Lorenzo Dominic LaValle has entered the world weighing 6lbs, 5oz. Nicole, Jionni & Enzo are doing great!” her rep shares.
The well wishes are already rolling in for the happy couple; Polizzi's castmate Pauly D sent her a sweet tweet Sunday morning. "Congrats @snooki And @JLaValle !!!! I'm Officially Uncle Pauly !!! #MyMeatballHadAMeatball," he wrote.
Snooki, 24, and LaValle, whom she met at Seaside Heights hotspot Karma in 2010, first shared their happy news -- that they are engaged and set to become parents -- with Us earlier this year.
The reformed party girl admitted she knew their announcement would cause a bit of a stir among her critics.
"I have different priorities now," the reality star assured Us. "I don't care what anybody else thinks. As long as I know I'm ready and he's ready."
Added LaValle, "We are not going to screw this up."
In a May chat with V magazine, Polizzi said she couldn't wait to welcome her little one into the world.
"Everyone will be surprised to see a different side of me," she shared. "I'm loving, caring, sensitive, protective and very maternal, no matter what people might think."
Since her big reveal, her Jersey Shore castmates have given a lot of thought to how they're going to accommodate the little one.
"We'll turn the smush room into a nursery," Vinny Guadagnino joked to Us in March. "We're all family. Whatever she needs."
