Ciara is one hot mama! The star showed off her wow-worthy post-baby body in a pair of Instagram photos over the weekend. Proudly donning two separate sets of Calvin Klein underwear in the pictures—one gray and one black—Ciara proved that not even the birth of her son Future Zahir Wilburn (born May 19) can come between her and her Calvins.

"After Delivering My Son I Feel Like There's Nothing I Can't Do. I Feel Like I Can Conquer The World. #ANewMe #NewMusic. So Proud To Rock #mycalvins 60lbs later!!" she captioned the close-up of herself in a gray sports bra and matching bottoms (above). "I feel so proud to say that 4 months after delivering a 9 lbs. 10 oz. baby, I can finally rock My Calvin's! #mycalvins," she wrote alongside the snap of herself lying in a bed of white wearing a black sweater, bra, and underwear (below).

Ciara previously told InStyle about her tips for getting in shape post-baby, revealing that she works hard but goes with the flow. "I think it’s about letting things be organic," she said. "You should set some goals and you should set up a pan to achieve your goal then just dial it in, but I don’t think you should overthink the process of getting there. You’ve got to have fun and enjoy being a mom." We think she looks incredible!
