Reality star Kim Zolciak revealed she is currently penning her first book.

Zolciak surprisingly responded, "Coming very soon."

The former Real Housewives of Atlanta star launched her own line of hair extensions and signature champagne earlier this year. Last month, she shocked her fans when she announced she is expecting twins with her fifth pregnancy.

E! News reported on Aug. 19 the reality star shared she was expecting and surprised to learn she is expecting two children because it was a natural conception.  

"I'm having twins and I couldn't be more excited," Zolciak told E! News. "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."

Zolciak is expecting with her husband Kroy Biermann, the 27-year-old Atlanta Falcons defensive end whom she married in 2011.

Zolciak gave birth to her fourth child, Kash Kade Biermann, a year ago on Aug. 15, 2012. Fourteen months prior she welcomed her first son Kroy Jagger Biermann on May 30, 2011. Zolciak also has two daughters from a previous relationship: Brielle, 16, and Ariana, 11.

She first revealed her fifth pregnancy during the season finale of her spinoff show Don't Be Tardy in June. The couple learned about their growing brood after she took multiple pregnancy tests in their home.
