Kim Zolciak is running with a much younger crowd these days! The Don’t Be Tardy star and her husband, Atlanta Falcons player Kroy Biermann, have welcomed their third and fourth children together. Zolciak announced the happy news today, sharing that the new twins have been named Kaia Rose (older sister) and Kane Ren (younger brother). With these two newest additions, Zolciak now has four kiddos younger than 3: 2.5-year-old Kroy Jr., 15-month-old Kash Kade, and now Kaia and Kane. Zolciak also has two older children — daughters Brielle, 16, and Ariana, 11 — from a previous relationship.
