Lorenzo LaValle is ready for his closeup.

Proud new parents Nicole "Snooki" Polizzi and fiance Jionni LaValle introduced their brand-new son Lorenzo Dominic LaValle via MTV on Wednesday.

In the sweet family portrait, the Jersey Shore starlet, 24, shows off her post-pregnancy curves in a leopard-print dress sits in a chair as she holds tiny Lorenzo (clad in a black-and-white checked onesie), with proud papa Jionni crouching alongside.

Born Aug. 26 in Livingston, NJ, Lorenzo weighed in at 6 lbs., 5 oz.

The happy couple broke news of their pregnancy to Us Weekly back in March.

"I have different priorities now," the reformed party girl 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."
