Former Jersey Shore star, Nicole “Snooki” Polizzi, showed off a 50-pound weight loss almost a year after giving birth to her son Lorenzo.

The reality star attended the Self Magazine Rocks the Summer red carpet event with her Snooki & JWoww co-star, Jenni “JWoww” Farley and showed off her slim figure.

The 25-year-old mother has documented her weight loss on Twitter, sharing pictures of herself working out vigorously trying to lose weight.

To those criticizing her weight loss, she previously wrote "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,” NY Daily News reports.

At the Self magazine event, celebrating the July issue with Ke$ha on the front, the duo bumped into another MTV star, Rivals II’s Diem Brown.

MTV reports Brown tweeted, “Saw the tini @snooki she looks amazing!"

Snooki’s son with fiancé Jionni LaValle is now 11-months old.
