Kim Zolciak and Kroy Biermann having another baby boy

"Don't Be Tardy for the Wedding" star Kim Zolciak finally revealed the sex of her summer baby. She and husband, Atlanta Falcons defensive end Kroy Biermann, are welcoming another boy to their brood in August.

"We'll save money since we already have all this boy stuff," "The Real Housewives of Atlanta" star tells Life & Style.

Kim has two daughters, Brielle and Arianna, and the couple welcomed little Kroy "KJ" Jr. last May.

"It's been a really good pregnancy, knock on wood," Zolciak recently tells Zap2it. "The easiest one so far."

Kim and Kroy wed in November, chronicling their trip to the alter on the new Bravo show, "Don't Be Tardy for the Wedding."

Any ideas for what Baby Boy Biermann's name will be?
