She's come a long way since her days on Jersey Shore.

Snooki, whose real name is Nicole Polizzi, hit the red carpet on Tuesday night for the Self Magazine Rocks the Summer Event in New York City, looking tinier than ever after losing an astounding 50 pounds.

In a white lace bustier by Shuku New York and a skin-tight, Moda Express high-waisted skirt, pint-sized Polizzi (who stands at just 4'8 tall) looked radiant as she posed for photos next to her Jersey Shore co-star Jenni "JWoww" Farley.

Since giving birth to son Lorenzo eight months ago, the 25-year-old has taken regularly to Instagram, uploading selfies of her ever-shrinking figure.

But Snooks (as she's affectionately known) has received some backlash from fans for her newly-svelte bod.

The notoriously loud-mouthed, reformed party girl has responded to critics, tweeting: "Everyone's saying the 'new fit me' isn't what I'm suppose to look what. I wasn't always a fatass kids. Get used to my fitlife, cause I love IT."

What do you think of Snooki's new look?
