Polizzi gave birth to her second child with fiancé Jionni LaValle, Giovanna Marie LaValle, just 13 days ago on Sept. 26. In her Instagram snap – in which she's donning a pair of leopard print leggings and a black tank top under a sweater – her legs look slim and her stomach flat.

Although Polizzi is looking as fit as did as she did pre-pregnancy, the reality TV star said that she’s not necessarily feeling as good as she looks.

"I'm still in pain—not as much as I was—but all the moms out there, you know, like right after you give birth, you're so scared to pee after, and you're scared to do your first poops, but then when you do, it's like, 'All right. I'm good. I feel better now,’” Polizzi told E! News. “It's always the anticipation of, 'Oh, my God, it's going to hurt. It's just so sore down there. And my boobies are going to fall off. But it's all worth it."

Polizzi and LaValle, who are also parents to 2-year-old son Lorenzo, are set to be married later this fall at The Venetian in Garfield, N.J. MTV Productions has already purchased a filming permit, as they’ll be covering it for Polizzi’s latest show on the network, Snooki & JWoww, with Jenni “JWoww” Farley.

"Along with still being a healthy pregnant woman, I still want to be strong and fit!" Polizzi said back in April, admitting she wanted to "look somewhat in shape" for the big day.
