Kim Zolciak and NFL husband Kroy Biermann announced on Monday that they are expecting twins.

The Real Housewives of Atlanta star and her husband of two years are already parents to two baby sons, Kroy Jr., who was born shortly after they married, and Kash Kade, who recently celebrated his first birthday.

Zolciak and Biermann currently star on their own reality television show, Don’t Be Tardy on Bravo, and confirmed her pregnancy on the show’s season finale in June.

Zolciak and Biermann spoke of their excitement at the news that they are 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. 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,” Zolciack told E! News.

Zolciack was already a mother of two daughters, Brielle,16, and Ariana,12, when she met Biermann. Earlier this year, Biermann officially adopted the two girls. The father of four (for now) tweeted his delight at the adoption in June.

“In order to keep balance you have to have priorities,” Biermann told E! News when asked why he decided to adopt Zolciak’s daughters.

After news broke that the sweet couple is expecting twins Monday night, Zolciak appears to have been showered by well wishes from fans and viewers. The expectant mother took to twitter early on Tuesday to show her thanks, saying that she and Biermann are “extremely grateful & blessed.”
