Nobody messes with Snooki's lil' meatball!

Pregnant reality star Nicole Polizzi, 24, got fed up with two rude Twitter users Tuesday, after one of them said that "the possible fathers of your child must be so excited" for her to become a first-time mom.

Polizzi, who is currently expecting a baby with fiance Jionni LaValle, shot back: "Such a lovely bitch, eh? Hooker."

When another Twitter user wrote, "I keep hearing you're going to birth a Dorito," Polizzi dryly responded: "Or a Cheeto."

The Jersey Shore star later tweeted a photo of herself with the caption: "I'll cut a bitch if you mess with my baby!"

When Polizzi broke the news of her pregnancy and engagement in a March 19 Us Weekly cover story, she explained why she isn't fazed by the public scrutiny. "I don't care what anybody thinks. As long as I know I'm ready and he's ready, I don't have to talk to anybody about it."

Polizzi doesn't mind giving up her party girl ways, either. "When I wasn't filming Jersey Shore, I hardly drank because I got into fitness and losing weight. When Jionni goes out and invites me, I say, 'No, go by yourself.' I just want to stay home and relaxed. No more peeing on porches," she told Us. "Those days are over."
