Snooki before her weight loss. Here she poses for casting photos for Season 2 of the MTV reality series, "The Jersey Shore."

Snooki has a sexy new body and she took to Twitter to show it off.

The Jersey Shore star posted pictures to her Twitter account, as well as her Facebook profile, showing of her post-weight loss body in a revealing, metallic monokini. The Italian diva vamped it up for the camera with a growling cat pose, showing of a taunt stomach and toned arms.

Snooki, aka Nicole Polizzi, posted a second photo of her in a blue monokini, wearing heels and pigtails. She was having fun at the photoshoot, making coy poses, and tweeted to designer Susan Holmes McKagan for the suit: Thank you @suholmesmckagan for the cute suit!

The 24-year-old reality star has credited diet pill Zantrex for her dramatic weight loss. She revealed on the Wendy Williams Show last month that she had slimmed down to 103-pounds. Her target weight is 98-pounds.

Zantrex is a fat burning tablet that has reportedly been used by other celebrities like Britney Spears. Side effects can include anxiety, cold sweats, nausea, diarrhea, increased heart rate and irritability.

Snooki recently told InTouch magazine that she was tired of all the celebrity blogs commenting on her weight. I didn't lose weight for them. I did it for me, she said. She told the magazine that, along with Zantrex, she has turned to diet and exercise.

When I work out and eat right, I feel healthier and happier, she said.

Rumors were swirling that she had taken drops of the controversial Human Chronic Gonadotropin (HGC) hormone, reports The Daily Mail. As of Dec. 6, 2011, the FDA prohibited the sale of HCG diet products.

Snooki denied the rumors. She tweeted: Glad to hear reports that say I look good =) but it's not because of HCG! Thanks @Zantrex!

The 4-foot, 9-inch reality star has been talking about her weight loss for the past few months now. Snooki has been known to tweet about her frequent gym trips and cutting back on unhealthy food and alcohol. She reportedly gets the energy to work out from herbal Zantrex-3 Fat Burner, the extreme energy pill for which she is a spokeswoman.

One of my followers asked if I was a paid spokesperson for zantrex...yes haven't you seen the ads in Star? she tweeted on Sept. 27.

Her dramatic weight loss has made the popular MTV personality unrecognizable to some, but she does not seem to mind. LOL so some girl comes up to me n goes 'you look like one of those girls from the jersey shows, but you look better.' Uhm thanks? Lmao, Snooki tweeted on Tuesday.

The new season of The Jersey Shore will premiere on MTV on Jan. 5.
