Snooki 'tweets' her thin self ...

Nicole 'Snooki' Polizzi has been really rocking her weight loss program and the results are quite dramatic.

The pint-sized Jersey Shore reality star has cut back on her drinking as part of her new training regimen.  Snooki claims that water is her new best friend.

Polizzi started working with a personal trainer in January and reports: "He kicks my ass all the time and I love it!"

The former cheerleader, who once suffered from anorexia and bulimia, is going by the book with her slim down plan.  She jokes: "As everyone's planning their night at the club, I'm wondering when Gold's Gym closes."
