Reality star Nicole 'Snooki' Polizzi has lost a whopping 50 pounds since giving birth to her first child 11 months ago.

Snooki, who stands at only 4'8" tall, has been working out to shake off her pregnancy weight gain since she gave birth to her son Lorenzo.

Snooki was photographed in New York on Tuesday, standing next to her co-star Jenni 'JWoww' Farley at the Self Magazine Rocks the Summer Event. She was wearing a white bustier top with a leather black skirt, matching high heels, and held a pink clutch.

She also tweeted a photo of herslef flexing her muscles with JWoww after the event.

The 25-year-old reality star had been regularly updating her fans on Twitter on her fitness progress. She tweeted last month: "Everyone's saying the ''new fit me'' isn't what I'm suppose to look what. I wasn't always a fata** kids. Get used to my fitlife, cause I love IT."

The petite star's slimming frame had worried some fans, with some worried that she may have a eating disorder. However, she dispelled those rumors by tweeting, "Strong is the New Skinny." She told Hollywood Life about her workout regime and healthier lifestyle. "I go to the gym five days a week and I eat healthy. I eat chicken, I eat salads, I eat vegetables, I just eat healthy and one day a week, I have my ice cream and my chips - but then the next day I go even harder at the gym. So I still live life but a healthier life."

Snooki originally starred in reality show "Jersey Shore" and currently stars in the MTV spinoff "Snooki & JWOWW".
