Just days after appearing on the Dr. Oz Show to share the secrets of her post-baby weight loss, Nicole “Snooki” Polizzi is showing off her figure in some fierce bikinis.

The reality TV star, who gave birth to her first child – son Lorenzo – back in August, posted some photos of Instagram where she looks fit and fab!

“Beach body ready!” the 25-year-old captioned the pictures.

Polizzi says the key to her weight loss wasn’t any big surprise – it just took hard work and commitment.

“I’m just a normal girl doing normal things,” she said. “If I can lose 42 lbs. after giving birth six months [ago], I mean, anybody could do it. You just need the dedication, and you need to want to have your body back.”

Congrats to this new mom on making the commitment to good health!
