With their pint-size cash cow Nicole “Snooki” Polizzi pregnant, frantic MTV producers are scrambling to change direction on their new “Jersey Shore” spinoff, sources say.

Once-hard-partying Snooki and her castmate Jenni “JWoww” Farley are shooting their new series in Jersey City. But with a Snook in the oven, the show’s plot has been forced to take a sudden turn.

“Plans for the direction of the spinoff have changed,” said a source. “Instead of partying, it will now show a whole new side to Snooki.”

The source added that MTV hopes the development could turn into another ratings boon as the roly-poly reality star tackles motherhood. “It will definitely give MTV ratings,” the source said. Another insider said the show is taping scenes in which Snooki drops the “bombshell” news to her “Jersey Shore” pals that she’s carrying a mini-guido while the others “try and look surprised.”

Meanwhile, sources say MTV will move ahead with a sixth season of “Jersey Shore,” set to begin shooting in “early summer.” It’s unclear how Snooki, and her bump, would figure into the new season. “They [may] throw [Snooki] a ‘Jersey Shore’ baby shower, or have her just pop in from time to time,” a source said.

Snooki, 24, publicly denied she was expecting on “GMA,” telling Lara Spencer, “I definitely do want kids, but I’m not pregnant.” Page Six revealed this week that Polizzi is carrying her first child by boyfriend Jionni LaValle and is nearly three months along. She’s also expected to confirm the news in an upcoming issue of Us Weekly.

Sources say Snooki is looking to cash in but has not yet lined up any partnerships with baby brands.

Meanwhile, multiple Snooki baby Twitter feeds popped up this week including @SnookisFetus, @Snooki__Baby and @SnookisSpawn, with tweets including, “I’m not kicking mom, I’m fist pumping.”

Reps for MTV and Snooki had no comment.
