Is Snooki getting smaller?

Lots of "wows" on the Web right now over Snooki's new size.

The MTV star and new mom (son Lorenzo is 11 months old) stepped out for a Self magazine party Tuesday night and looked tinier than ever.

She showed off her sleek shape on the cover of Us Weekly in March, when she had shed 42 pounds. But we still aren't used to her new look.

On Tuesday night, she said it's all about becoming a gym rat instead of a party girl.

"I work out in the gym seven days a week. I go with my trainer five days a week, I have a treadmill downstairs or I do crunches," Snooki, 25, told People at SELF Rocks The Summer Party in Manhattan. "I try to do something at least once a day." Once famous for going clubbing and her stumbling Jersey Shore antics, Snooki now seems to be a changed women.

"It's a part of my life – being fit is [a priority]," she said. "First was partying, now it's my son and working out."
