(USATODAY) -- Kim Zolciak may need a new house.
The reality star is expecting twins, according to E! News.
The Real Housewives of Atlanta star, 35, says she "couldn't be more excited" about adding two more to her brood with her husband, Atlanta Falcons defensive end Kroy Biermann.
"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."
The couple have two children together, Kroy Jr., 2, and Kash Kade, 9 months, and Biermann has officially adopted Zolciak's daughters Brielle and Ariana from previous relationships. The reality star first revealed she was pregnant on the finale of her spin-off show, Don't Be Tardy, and in July she shared a photo of her growing stomach.
"I can't believe I am going to be a mom to six children," she told E! News. "It's going to be very busy but it's a dream come true."
