Ciara gave birth to her son Future just four months ago and now the #SASYmom is showing of her killer curves and super fly stomach in a new Calvin Klein ad.

“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!!,” CiCi posted on Instagram.

Can you believe Ci lost 60lbs in just four months!!! She looks fantastic! The “Ride” singer also posted another pic in her undies to promote the new #MyCalvins movement.

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

This girl deserves a round of applause!
