Hot Mama! Snooki Shows Off Flat Stomach 4 Months After Giving Birth

Nicole "Snooki" Polizzi's post-baby body just keeps getting better!

The Jersey Shore star showed off a flat stomach and lean arms while posing for a selfie in a sports bra and leggings.

"Almost 4 months post partum and so happy with my results. I still have loose skin and stretch marks on my belly, but it's all worth it for my beautiful babies," Snooki wrote on Instagram.

"Staying fit during pregnancy was the best thing I could ever do. Now it's time to build that muscle for summer 15!"
