Pregnant Snooki Tweets About Her Unborn Baby (PHOTO)

Don't mess with Snooki -- or her baby!

The petite and pregnant "Jersey Shore" star showed her tough side on Twitter Tuesday, posting a photo of herself ready to fight anyone who upsets her unborn baby.

Snooki, whose real name is Nicole Polizzi, is expecting her first child with fiance Jionni LaValle. After weeks of speculation, Snooki confirmed her pregnancy and engagement on the cover of Us Weekly in March.

"I have different priorities now," Snooki told the magazine. "I don't care what anybody else thinks. As long as I know I'm ready and he's ready."

It seems the wild child of MTV's "Jersey Shore" is preparing for her little meatball to arrive, recently tweeting that she can't wait to find out the sex of her baby.

"Ah I can't wait to see my little one whose either going to be a dedicated cheerleader like mommy or a strong wrestler like daddy," she tweeted April 2.
