In three weeks, Nicole "Snooki" Polizzi of "Jersey Shore" fame and fiancé Jionni LaValle will be first-time parents.

Even though Snooki is giddy about her new baby boy, who has already been named "Lorenzo," she has some fears about being a new mom.

 "I'm nervous that I'm not going to be a good mom," she told In Touch magazine. "I just really hope I know what I'm doing!"

The reality star said being pregnant has been crazier than any after-hour shenanigans at the Jersey Shore. "At the Shore you're going to hook up, get into a fight or go to jail. You only have three options. But being pregnant you have no idea what's going on!"

Snooki's been preparing for her son's arrival with apps that tell her what she should be eating and how big the baby is. However, she has not been attending Lamaze classes!

"Lamaze is bull****," she said. "They teach you how to breathe. Are you really going to be worrying about how to breathe when you're having a baby? No! You're going to be screaming and throwing s***."

"I don't think anyone really knows what they're doing with the first kid," she explained to In Touch magazine. "But I think I will be a good mom. I hope so!"

And while the soon-to-be mom can't wait for her baby's arrival, Snooki jokes that she's most looking forward to "being a MILF, for sure."

On Aug. 22, Snooki tweeted, "Errands with Jionni! Lorenzo should be here anyday now."

And cast mate Pauly D can't wait to be the little guy's "uncle."

"When are you poppin this baby out??? I wanna play with him!! #TeamUnclePauly," he tweeted on Aug.18.

Snooki responded, "Tell me about it! I'm legit a meatball!"

Pauly D told Hollywood Life, "I told her to text me the second she has contractions and I am there!"
