JWoww indeed!

When fans tuned into the season four premiere of MTV's Jersey Shore on Thursday night, they couldn't help but notice that one of the cast member's body and face looked remarkably different.

In addition to dropping what appeared to be a significant amount of weight, Jenni "JWoww" Farley's features seemed enhanced by injectables like Botox to her crow's feet and forehead, as well as possible fillers around her nose and mouth.

The buxom brunette has always been open about her large breast implants, proudly raving on Thursday episode, "These babies are 700 cc's and they're staying 700 cc's."

Back in December of last year, Farley, told Us Weekly that while she still enjoys junk food and alcohol, the secret to maintaining her physique is moderation and regular workouts.

"I'll still eat junk food, cheesecake, cheese, pizza, but just lower amounts of it," she told Us at the Ab Cuts event in NYC in December. The star said she takes the nutritional supplement once or twice a day. "It's for overall health and for feeling good about yourself."

For workouts, the MTV personality has a special relationship with her trainer. "My boyfriend trains me," the 24-year-old said. "He's a big bodybuilder."
