Kim Zolciak Twins Due Date Approaches Fast: Reality Star Proudly Displays Baby Bump at Nine Months Pregnant (PHOTO)

The countdown has begun for reality star Kim Zolciak. The former "Atlanta Housewife" is nine months pregnant and proudly showed off her baby bump to her Twitter followers, the Daily Mail reports.

"The twins will be here this month and we are soooo excited and I'm soooo over being pregnant!" she tweeted. "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 and her husband Kroy Biermann already have two sons together -Kroy Jr., 2, and Kash, 15-months. Zolciak also has two other children with ex-husband Dan Toce - Brielle, 16, and Ariana, 12.

The couple recently celebrated their second wedding anniversary at home because Zolciak is "ready to pop."

"Happy 2-year anniversary to the most incredible husband ever" she tweeted along with a picture montage of their wedding. "I'll never forget your face as I walked down the aisle. I'll never forget the feeling I felt the second I saw you. Kroy you are my best friend, my soulmate, and my lover. I am forever grateful we found each other. I look forward to spending the rest of our lives together and enjoying our 6 (holy s**t) babies! That you for loving me like you do."

She previously told E! News during an August interview that she had no idea she would be having two more kids.

"I was completely shocked," she said. "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. I can't believe I am going to be a mom to six children. It's going to be very busy but it's a dream come true."

The reality star found out she was expecting for the fifth time on her reality show "Don't Be Tardy," and said she took over a dozen pregnancy tests to make sure it wasn't a false alarm.

"Pregnant, pregnant, pregnant, pregnant, pregnant, pregnant," she read the results to Biermann on the show. "Kroy, we have not one negative test."
