Forget a bun, there may be a meatball in the oven!

“Jersey Shore” star Nicole “Snooki” Polizzi is pregnant, according to a report in Star magazine.

The pint-sized guidette and self-proclaimed meatball is reportedly expecting her first child with boyfriend Jionni LaValle, according to an insider.

“She is pregnant and has only told her closest friends and some family,” an insider said.

But during an interview today on the “Opie & Anthony Show,” the reality star said there is no baby on the way.

“The media says what it wants to grab headlines and make money,” she told the radio hosts.

The source told Star that Polizzi, 24, has been hinting that she “has a big announcement coming.”

Polizzi added to the speculation in a recent posting on her Twitter account.

“Late night craving…yogurt hits the fricken spot ! Mmmmmm,” Polizzi tweeted on Jan. 25.

According to Star, Polizzi’s upcoming spin-off show with fellow “Shore” personality Jenni “JWoww” Farley is going to be in for changes due to her alleged pregnancy.

“[MTV] are having to redo the creative direction of her spin-off because of her pregnancy,” it was reported.

The spin-off also hit a snag yesterday after Hoboken Mayor Dawn Zimmer denied a request for MTV to film in her city.
