Kim Zolciak's estranged husband, Kroy Biermann, accused the former Real Housewives of Atlanta star of "psychological" abuse of their children in his plea for sole custody, Us Weekly can report. A rep for Zolciak adamantly denied the claims. On Friday, August 15, Biermann, 39, filed court documents in his ongoing divorce from Zolciak, 47. The exes split in 2023 after 12 years of marriage. They have yet to work out a settlement. The exes share four children: sons Jagger "KJ" Jr., 13, and Kash, 12, and twins Kaia and Kane, 11.
