Brielle Biermann is maintaining her wedding plans with fiancé Billy Seidl for this November, sources confirmed, proceeding despite her younger brother KJ Biermann's recent arrest and indictment.KJ Biermann, 15, was arrested on August 17 on felony charges of aggravated sodomy and aggravated sexual battery. He was formally indicted on seven felony counts on September 3 by a grand jury in Georgia. His charges include aggravated child molestation, aggravated sodomy, aggravated sexual battery against a child under 16, and false imprisonment.The alleged incident reportedly occurred on April 23 at a fitness center in Alpharetta, Georgia, involving a female classmate. Court documents state the accuser claimed KJ Biermann attempted sexual intercourse multiple times and disregarded her repeated objections.KJ Biermann has pleaded not guilty to the charges, and his legal team is seeking to have his case moved to juvenile court. His attorney, Jason Sheffield, argued in a September 8 filing that KJ is too immature to face adult charges, which carry a mandatory minimum sentence of 25 years to life imprisonment. Sheffield stated that at 15, KJ is an adolescent whose development is ongoing. KJ is scheduled for a bond hearing on Friday.Brielle Biermann, 29, became engaged to baseball player Seidl in February 2024. While she has remained largely private about the wedding details, sources close to the situation indicate the ceremony is still on track for November.Kim Zolciak, mother to Brielle and KJ, has publicly supported her son, calling the allegations “reckless and deeply troubling.” Her representative stated that KJ categorically denies the accusations, has passed a voluntary polygraph test, and that no DNA belonging to him was found. Zolciak expressed confidence that the facts and evidence will establish the truth and cautioned against the consequences of false accusations.Kroy Biermann, father to Brielle and KJ, has not yet commented on his son's arrest or the charges. Both Zolciak and Kroy Biermann have been observed appearing stressed following the developments.
