Jionni LaValle, Nicole "Snooki" Polizzi

Nicole "Snooki" Polizzi and her fiancé Jionni LaValle are expecting their second child, Us Weekly reports. The couple are already parents to 19-month-old Lorenzo, whose birth was documented on her reality show Snooki & JWoww.

"Jionni and I were trying to have our second baby since November, so every month we kept taking tests," Snooki tells the magazine. "I'm due in the fall around my wedding time. Busy year!"

The couple announced their engagement and first pregnancy in March 2012. Snooki says she has no plans to push the wedding back any longer. "I can clarify that our wedding is still on, and we are madly in love with each other," Snooki says. "We've waited long enough and cannot wait."

Characters we used to hate

The reality star also revealed she plans to stay active during her pregnancy, in hopes of helping keep her labor short (and her looking fit on her big day). "[I'm] still working out with my trainer, safely, obviously, and being more conscious of the bad foods I eat," she says. "I refuse to be in labor again for 27 hours, and being active definitely helps that.

"I also want to look somewhat in shape for my wedding," Snooki adds. "So along with still being a healthy pregnant woman, I still want to be strong and fit!"

And talk about perfect timing! Snooki's Jersey Shore co-star and BFF Jenni "JWoww" Farley is also expecting a daughter with fiancé Rodger Mathews. "Jenni and I always talked about being pregnant together," Snooki says. "I'm so excited to go through this experience with my best friend!"
