Nicole "Snooki" Polizzi has "grown up a lot" now that she is pregnant.

The reality TV star recently confirmed that she is expecting her first child with fianc Jionni LaValle.

People magazine reports that partaking in wild Jersey Shore debauchery no longer appeals to Snooki.

"I guess [pregnancy] just made me more mature," Snooki told reporters Thursday at a press conference for her new show Snooki & JWoww vs. The World in New York City. "It's different because now I'm not drinking. I'm usually partying and going to clubs but pregnancy made me grow up a lot."

To her surprise, Snooki didn't feel too ill at the outset of her expectancy.

"I hardly threw up," she shared. "I was just very tired and cranky."

The star had bizarre cravings for pickles early on, but now has an intense hankering for other foods.

"[I eat] a lot of fruits and Italian icies no pickles," Snooki said.

The buxom star has also given up one key beauty treatment.

"I haven't tanned since August," she revealed.

Snooki & JWoww vs. The World also starring Jenni "JWoww" Farley will premiere on MTV June 21.
