Kim Zolciak Reveals Post-Baby Body Via Twitter [Photo]

Real Housewives of Atlanta star Kim Zolciak gave birth to her fourth child three weeks ago, but you probably wouldn’t believe it based on photos posted by her 15-year-old daughter Brielle.

Zolciak, 34, and her NFL husband Kroy Biermann welcomed their second son Kash Kade Biermann on August 15. On September 1, Kim’s oldest daughter, Brielle, showed off her mom’s post-pregnancy bod in an image uploaded to Twitter.

“Seriously… who looks like this after 2 weeks of having a baby?” Brielle asked, sharing a photo (seen below) of Zolciak wearing a black tank top and matching drawstring sweat pants that revealed a much slimmer figure after baby Kash’s birth.

According to the NY Daily, Zolciak gained 50 pounds during her last pregnancy when she was carrying son Kroy Jr., who is now 15 months old. In addition to Brielle, Kash, and KJ, the reality star is also mom to a 9-year-old daughter, Ariana.

While there is no word yet on how she lost the weight, Celebuzz writes that she most likely did it without the help of her personal trainer, Jim Launer, who recently moved to New York for the NFL season.

In related news, Zolciak will have a reduced role in the upcoming fifth season of The Real Housewives of Atlanta in order to spend more time with her family.

The mom of four recently took to Twitter to write:

I have a little break from filming since I had the baby but back at it soon enough!! so u will get to see just how cray cray my house is!
