She's rumored to be a few months along but has been keeping her great expectations quiet so as not to interfere with some "lucrative personal appearances."
Snooki's rep is mum on the belly rumblings.
The couple welcomed son Lorenzo Dominic LaValle in August 2012, but the slimmed-down, grown-up brunette has made it clear that's just the beginning.
"I definitely want to pop them out one after another, but we kind of want to get married first and then have our baby, but if it happens it happens," she told People earlier this month. "Babies are awesome and I want three more."
Snooki, who penned the recently released book "Baby Bumps: From Party Girl to Proud Mama, and All the Messy Milestones Along the Way," is actively planning a "Great Gatsby"-themed aisle-walk set for this fall.
"I got an elegant ball gown for the church and a mermaid-style dress with a poufy train for the reception," she tells In Touch. "Everyone expects me to wear glitter and leopard, and I'm like, 'Maybe if I got married four years ago.'"
Snooki, whose BFF and reality show partner JWoww is awaiting the imminent arrival of a daughter, says she's trying to stay on budget and refuses to use a wedding planner.
"I'm trying to save money -- I'm so cheap!" she admits. "Plus, I don't like people telling me what to do!"
