Apparently inspired by requests for more, the 35-year-old took to Instagram Sunday to share another snap of her pregnant belly.
"Sooooo with all the request [sic] I finally decided to post My baby bump today!" Zolciak wrote. "The twins will here this month and we are soooo excited and I'm soooo over being pregnant! #countingdownthedays."
Zolciak announced in June that she was pregnant for the fifth time with husband Kroy Biermann. It was later revealed she was expecting twins.
"I'm having twins and I couldn't be more excited. I was completely shocked. I had no idea. It was a natural conception, but twins do run in the family, so I guess I shouldn't have been surprised," she said at the time.
Zolciak already has four children -- Brielle, 16, and Ariana, 12, KJ, 2, and Kash, 1.
So how big is her belly?
"Hubby just measured my belly OMG!!! 48 inches around!! And not ONE stretch mark!! I know stretch marks r genetics but I have some tricks!" she tweeted ahead of her baby bump pic.
