Kim Zolciak, a former star on the reality show "The Real Housewives Of Atlanta," gave birth five months ago, and showed off her weight loss in a cut-out swimsuit.

“I’m obsessed with Have Faith swimsuits,” she wrote as the photo caption. 

Zolciak and her husband, NFL player Kroy Biermann, 26, welcomed their son Kash Kade back in August.

This is not the first time she has shown off her slimmed down physique after having her fourth child. 

Zolciak was featured in the January issue of Life & Style magazine, where she said, “I’ve lost 30 pounds. I’m only 5 to 8 pounds above my weight before I got pregnant.”

When asked how she reached her weight loss goal, she stated, “I never sit on the couch.”

“I think breast-feeding helped me lose some weight, and I was really busy as soon as I got home with Kash. I went straight into filming my spinoff show, ‘Don’t Be Tardy,’ and I’m sure that helped. I just never sat still!”

But Zolciak adds that she watches what she eats. “I don’t eat red meat or pork or much dairy, and I always eat in moderation.

"I’m a size 4 right now, and my goal is to get down to a size 2.

"I’m accepting that I’m going to have to hit the gym — my girls [Brielle, 15, and Arianna, 11] laugh and say there’s no chance, but I really think I’m going to have to.”

While her weight loss is impressive, not all her followers on Twitter were pleased with Zoliak posting her slimmed down body on the social media site. 

“Way too old for this. I feel sorry for all her kids,” one user wrote.
