Polizzi, 24, is about four months pregnant, according E!, and she wasn't truthful on her "Good Morning America" appearance just a few weeks ago.
“I definitely do want kids, but I’m not pregnant ," Snooki said on the show. "Being pregnant should be a real thing and a happy thing, and I’m not.”
The baby's father is Polizzi's boyfriend Jionni LaValle, according to E!
If Polizzi really is pregnant, it is unclear how it will affect the new "Jersey Shore" spinoff show she is shooting in New Jersey with roommate Jenni "JWOWW" Farley.
"Nicole and Jenni began filming last week and moved into their new digs with animal print furniture in tow. Things are going great thus far," Polizzi's representative told People.
When asked about pregnancy rumors, the rep had a simple "no comment" for CNN and People.
