Snooki shows off slim body, baby Lorenzo on Twitter

Nicole “Snooki” Polizzi slimmed down before getting pregnant, and it seems now that she has given birth the “Jersey Shore” star plans to keep her skinny figure intact.

The reality star tweeted a picture in a tight skirt, showing off her small waist, before a night out on Sept. 22. Polizzi posed wearing a leopard-print top and stood with three of her friends.

She explained to one fan that breast-feeding helped her shed some of the weight she gained during pregnancy:

“I've lost a lot of my baby weight!” she wrote about breast-feeding. “Also it's the best for him!”

She has also been at the gym, doing a "#postbabyworkout,” she wrote on Sept. 21.

And the new mom hasn't just been showing off her weight loss on Twitter, she has also been busy posting photos of her newborn Lorenzo, who was born Aug. 26.

“Goodnight my beautiful boy,” she wrote alongside a photo of her son sleeping in her arms.  “Love you,” she added.
