Kim Zolciak demands drug test for ex-husband in bitter divorce battle.

Kim Zolciak has asked a judge to force her estranged husband, Kroy Biermann, to take a five-panel hair follicle drug screen due to her concerns for the safety and well-being of their four minor children while in his care, citing his marijuana smoking as the source of her fear. Both Kim and Kroy filed separate petitions for divorce last week, with both asking for sole physical custody of their kids, and Kroy asking for sole legal custody as well.
