Snooki's secret pregnancy is a joyful time for the pint sized star, but it is causing some major upheaval for her new Jersey Shore spin-off reality show called Snooki and JWOWW Vs. the World.

Star magazine was the first to report a month ago that Nicole "Snooki" Polizzi was expecting a baby, with a source close to her revealing the bombshell news.

"She's pregnant and has only told her closest friends and family," the insider told Star magazine in its February 1 issue.

With her MTV co-star Jenni "JWOWW" Farley, Snooki has been filming her new reality show, but the baby is completely changing the show.

"This would be part of the story," a source exclusively told Star magazine.

"They are having to redo the creative direction of her spin-off because of her pregnancy."
