Snooki Steps Out Without Makeup -- See How She Looks!

Diet and exercise sure does the body (and skin) good! 

On Monday, Nicole "Snooki" Polizzi was spotted leaving the gym makeup-free in East Hanover, New Jersey. 

The reality star looked happy and healthy as she smiled for cameras sporting hot pink leggings and a black T-shirt. 

Snooki's dropped more than 40 lbs since giving birth to her and fiance Jionni LaValle's first child together, Lorenzo -- and she looks amazing!

But the weight definitely didn't just fall off. Polizzi's personal trainer, Anthony Michael, keeps the tiny star fit with regular, grueling workouts. 

Snooki posted a photo of herself after the gym on her Instgram with the caption, "Rockin pink gear today. The least I can do is look bright and tan as I'm feeling like death my first day back to training in a week."
