The ex-Real Housewives of Atlanta star, and her husband, NFL player Kroy Biermann have had quite a bit of time on their hands the past few months after she was unceremoniously booted off the RHOA island and it seems that baby making has become her new past time.

And Kim also didn’t waste any time revealing the names of her new bambinos…

The girl?s name is Kaia Rose, which Zolciak wrote was in honor of ??Psychic? Rose who is like a grandma to me?? and she named her new son after her OBGyn who has delivered FIVE of her now SIX children.

The couple celebrated their 2 year anniversary 2 weeks ago and as you know, the fertile couple already has two sons together, Kroy Jr., 2, and Kash, 15 months.? The twins’ arrival makes Kim and Kroy the proud parents of 4 new kids in two years.

Biermann also adopted Zolciak?s two daughters, Brielle and Arielle from her two previous relationships.
