Photo: Jersey Shore star Deena Cortese dons a Baywatch bikini after dropping two dress sizes - The reality star, has lost 15 pounds, says she is the "guidette Pamela Anderson�

She was the subject of cruel taunts online over her weight, but now “Jersey Shore” star Deena Cortese is having the last laugh.

Cortese has shed 15 pounds in recent months and dropped from a size 8 dress to a 4 through healthy eating and exercise.

And she’s flaunting her new figure by donning the iconic swimsuit of her idol- “Baywatch” star Pamela Anderson

“I loved Baywatch when I was younger. I always wished I was her,” Deena tells In Touch magazine,  who she posed up for this exclusive photo. “I’m the guidette Pamela Anderson.”

But Deena wasn’t always this confident. “I’ve always struggled with my body image,” she admits. And after watching past seasons of her hit show, Deena says, “My weight was getting out of control, and I knew it was time to do something about it.”

And now she admits that she is more confident than ever.

“I’m happy with myself, and that’s the only thing that really matters,” she adds.
