KJ Biermann has been accused of having sex with an underage relative in a bombshell, never-before-known revelation from court.

The 15-year-old — who is the son of “Real Housewives of Atlanta” alum Kim Zolciak and retired NFL star Kroy Biermann — appeared in Georgia’s Fulton County Superior Court on Friday.

During the hearing, Deputy District Attorney Caitlin McGillicuddy shockingly revealed that investigators previously found videos on KJ’s cellphone that allegedly depicted him having penetrative sex with a family member under the age of 12.

McGillicuddy claimed there were “multiple encounters” on video that were discovered on the device and that they allegedly showed KJ using “predatory, derogatory” language toward the victim.
