Snooki gave birth to son Lorenzo Dominic in August, and she's already showing off her post-pregnancy slim down with newly posted pics on Twitter. The Jersey Shore star posed in tight black jeans, sunglasses, and a leopard print headband, and we don't think we've ever seen the pint-size reality star looking so skinny!

Now that she's a mom she must not be taking in thousands of calories from alcohol and hard partying!

Not only that, but apparently the pickle-loving princess is religiously hitting the gym. The 24-year-old was up bright and early yesterday to fit in some fitness, tweeting, "Cardio Time."

Lookin' good Snooks!
