"Jersey Shore" may be over, but Deena Nicole Cortese is still getting ready for the beach!

The 26-year-old reality star took to Twitter today to show off her in-progress bikini bod, posting a photo of her in a skimpy yellow two-piece.

"Almost Aruba ready," she tweeted about the photo. "Couple more weeks to go! Couple more pounds to lose!"

While it sounds like Deena is on a mission to drop a few more lbs, we gotta say she's already come a long way from her days in Seaside Heights ... just like costar Snooki and her own weight loss.

Last October, Cortese said she had lost 15 pounds and went from a size 8 to a size 4 after being constantly bullied online for her looks.

"If you’re a little heavy, online bullies will treat you like crap," she said at the time. "It’s sad. And it really hurts."

See how she's changed since her MTV debut in the gallery above. With her weight loss and veneers, she's a totally different girl!
