Ciara Shows Off 60-Pound Weight Loss After Having Baby

— -- Ciara welcomed her first baby, Future Zahir Wilburn, just four months ago in May, but that hasn't stopped the singer, 28, from dropping some serious baby weight.

In fact, she's lost 60 pounds, and posted a revealing pic in only some Calvin Klein underwear.

"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 wrote on Instagram.

In another photo, she wrote, "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."

Ciara and rapper Future welcomed the bundle of joy on May 19 and she announced the news on Facebook, spilling that the baby weighed 9 pounds, 10 ounces.

This dramatic weight loss shouldn't surprise anyone. She told W magazine earlier in the year that the plan was to get back in shape quick.

"As soon as the body says hit the gym, I’m going to hit the gym. I've been having a lot of food fun," she said. "I don’t want to sound too cocky, but I consider myself superwoman."
