Jersey Shore's Nicole "Snooki" Polizzi, 24, and her fiancé, Jionni LaValle, 25, introduce their 6 lb. 5 oz. baby boy Lorenzo Dominic in this week's issue of PEOPLE, where the new parents share exclusive photos and talk about trading late-night partying for early-morning feedings. In Polizzi's suddenly mommyfied world, "bottle service" has a whole new meaning. "When I got pregnant, everything changed," she tells PEOPLE. "The partying is long gone. I'm a new person."

PEOPLE: This was not planned, right?

Nicole: I always wanted to get married and have kids early. I was aiming for 26, so I'm two years early.
Jionni: We never thought twice!
Nicole: Everybody said, 'What's gonna happen [with your career]?' I was like, 'I'm having this kid. If it ruins everything, I'll get a normal job from 10 to 5.' I didn't give a s---.

PEOPLE: You were in labor for 26 hours.

Jionni: She did her makeup in the delivery room.
Nicole: Before I was pushing, I put bronzer on and [false] eyelashes. I wanted to look pretty for him!

PEOPLE: Any chance you'll hit a club soon?

Nicole: I still want a glass of wine and to have fun, but I have no intentions of going to a club. I'm over it. I'd rather stay home with our son. That's fun.

PEOPLE: Have you had a drink yet?

Nicole: It's too early. I just gave birth! I want to make sure it's the right time, because I'm recovering. It hurts!
Jionni: She's definitely more of an addict for Slim Jims.

PEOPLE: Speaking of diet, how will you get back into shape?

Nicole: I'm definitely trying to eat healthier…and I can't really work out for six weeks, but then I'll start hard-core training. I'll get a trainer or I'll try a boot camp or go back to hot yoga. I gained 35 lbs., but I've already lost 10. I'll bounce back.

PEOPLE: Any wedding plans yet?

Nicole: He has a huge family, so it's probably going to be a big wedding, but I want it to be normal. No helicopters! And I'll wear something sparkly, blingy and white. And my bridesmaids will wear leopard print.
