The diminutive `Jersey Shore` star - whose real name is Nicole Polizzi - and her boyfriend of just over a year, Jionni LaValle, are expecting their first child together and the pregnancy will feature in her new reality TV show, a spin-off with co-star Jenni `J-Woww` Farley.
A source told America`s Star magazine: "She is pregnant and has only told her closest friends and some family. She`s been telling people that she has a big announcement coming.
"They are having to redo the creative direction of her spin-off because of her pregnancy."
Snooki recently revealed she is looking forward to leaving her partying ways behind to get married and have a baby with Jionni although she wasn`t expecting it to happen so soon.
She said: "I`m still waiting for that ring, I swear to God. I`ve been telling him this for months now!`
"I live my life crazy partying whatever, but I`m ready to settle down and have a little baby.
"[I`m giving him] two years. I`m 24 now. He has until 26 to ask me. If he doesn`t ask me, I`m asking him!`
Snooki has previously hooked up with `Jersey Shore` co-star Mike `The Situation` Sorrentino and Vinny Guadagnino on the show.
