Nicole “Snooki” Polizzi may be best known for her carefree, club-hopping ways, but the Jersey Shore star – who recently confirmed that she and fiancé Jionni LaValle are expecting their first child – says that having a baby on the way has changed her.
“I guess [pregnancy] just made me more mature, Polizzi, 24, told reporters while promoting her new MTV show Snooki & JWoww Thursday in New York City.
Joined by Jenni “JWoww” Farley and Jersey Shore cast mate DJ Pauly D, the reality star explained just how much her behavior has been altered.
“It’s different because now I’m not drinking,” Polizzi notes. “I’m usually partying and going to clubs but pregnancy made me grow up a lot.”
