The noticeably leaner meatball recently dropped 15 pounds and two dress sizes from regular dieting and exercise after struggling with her body image for years. She shares that watching herself on Seasons 3-5 of “Jersey Shore” is what inspired her to slim down: “My weight was getting out of control, and I knew it was time to do something about it.” Negative Internet chatter didn’t help her confidence either. “If you’re a little heavy, online bullies will treat you like crap,” she says. “It’s sad. And it really hurts.”

We highly doubt she’ll be hearing a peep out of those cyber-jerks’ mouths now–after all, they’re too busy eating their words.
