Snooki lost weight in the off time between Jersey Shore seasons, and she celebrated by posting photos of herself mugging for the camera while wearing her mom’s high heels and a button down shirt. She looks good and you can see the difference in her face, but she’s still Snooki and the duck face and the completely uncalled for smug is still strong. The pint sized wonder has been tweeting about how she’s going to the gym and told People that she’s switched out high calorie drinks like margaritas for vodka and seltzer.

“As everyone’s planning their night at the club,” she recently Tweeted, “I’m wondering when Gold’s [Gym] closes.”

In fact, for the past few months, the 4’9″ reality TV star has been working hard to tone up and lose a few unwanted pounds.

“Two months before season 1 started, I was 100 lbs. and really happy with myself,” she told PEOPLE in January. “Then I went on the show and it was like, ‘Oh man. We’re partying all the time, and who wants to go to the gym when you’re on vacation?’ ”

At that point, Polizzi told PEOPLE she was working with a trainer and trying to eat healthy foods. She has also been experimenting with Zumba, a dance class, and even showed off her gymnastics skills at WWE Raw.

“I definitely want to get in shape and be healthy again,” the reality star, 23, said. “But it’s really hard to eat good when you’re traveling because you see fast food – and you want to go to this restaurant and that restaurant.”

Still, “[I have] egg whites in the morning and chicken and salads,” she said. “And if you do drink, it’s gotta be clear liquors.”

Now, instead of throwing back Long Island Iced Teas or margaritas (“Which are, like, a million calories,” she notes), Snooki’s new drink of choice is a lighter option: vodka with seltzer water.

But with her trip to Italy looming (the cast will head overseas soon to film season 4), she knows the temptation to cheat on her fitness regimen will be huge.

“All we’re gonna eat is pasta,” she said. “I’m very, very scared – drinking wine and having spaghetti all day [would] throw me off course.”

The other day at Red Lobster I asked to see the nutritional information. They have a giant margarita called the Lobsterita that’s 890 calories, no joke. (A regular frozen margarita is around 500 calories, so get it on the rocks. Also, never eat the Lobster, Artichoke and Seafood Dip – that’s 1,200 calories.)

Snooki lost most of this weight in the last three weeks. I found a photo of her on 3/30 (below) and she looked about the same as before. She posted these photos to Twitter on 4/20, only three weeks later. I’m thinking she did more than just eat chicken salads and egg whites to lose weight that fast, but she’s so short at 4’9″ that it’s possible she lost around 10 pounds. Still, she has a flexible relationship with the truth. She recently tweeted that she got extensions for the “first” time on 4/21, and claims that she’s not wearing makeup in this photo.
