KJ Biermann is the oldest biological son of reality-TV personality Kim Zolciak and former NFL player Kroy Biermann. He grew up in front of television cameras on The Real Housewives of Atlanta and the family series Don’t Be Tardy, and he later became known for high-school football.
Interest in KJ has increased in September 2026 because of an active Georgia criminal case involving serious allegations. Because KJ is 15, this profile separates established biographical facts from allegations and makes clear that criminal charges are not proof of guilt.
Background: Who Is KJ Biermann and Why Are People Searching for Him?
KJ Biermann’s full name is Kroy Jagger Biermann Jr. He is the first biological child of Kim Zolciak and Kroy Biermann. His parents became a familiar television couple after appearing on Bravo’s The Real Housewives of Atlanta, where Kim was already a cast member and Kroy was introduced to viewers during their relationship.
KJ was born in the Atlanta area and became part of his family’s television story from infancy. Bravo identifies May 31, 2011, as his birthday, while IMDb lists May 30, 2011. Because two published sources give different dates, the exact birth date should be treated as unconfirmed; the year 2011 and his age of 15 in September 2026 are clear.
His family later became the focus of Don’t Be Tardy, a Bravo reality series that followed Kim, Kroy and their children. KJ therefore became recognizable to viewers without building a separate entertainment career of his own. IMDb credits him as appearing as himself on the family series.
Key point:
KJ is primarily known publicly as the son of two recognizable television and sports figures and as a high-school football player. He is not an established adult entertainer or professional athlete.
Latest Update
Here is what is currently known about KJ Biermann.
KJ is currently at the center of an active legal case in Fulton County, Georgia. A grand jury indicted him on September 3, 2026, on seven felony counts connected to allegations arising from an April incident. Reports say the charges include aggravated child molestation, aggravated sexual battery, aggravated sodomy, three counts of sexual battery against a child under 16, and false imprisonment.
KJ’s attorney has said the teenager intends to plead not guilty and has challenged the allegations. His legal team has also asked the court to move the case into juvenile proceedings rather than having KJ prosecuted as an adult. That request is a legal motion, not a ruling that the allegations are true or false.
On September 11, a Fulton County judge set bond at $200,000 and imposed strict conditions. Reports say those conditions include GPS monitoring, virtual schooling, surrendering his passport, restrictions on phones and social media, and no contact with the alleged victim or other minors.
Important legal clarification:
The allegations described in this section remain allegations. KJ has not been convicted, and his attorney has stated that he intends to plead not guilty. Claims made by prosecutors, the defense, or other parties should not be presented as established facts.
The case is the main reason searches for “KJ Biermann” have increased in September 2026. Recent reporting has also described additional allegations raised during bond proceedings. Those claims have not resulted in a conviction and should be understood as part of the ongoing legal process rather than proven conduct.
Full Profile
Family and Early Life
KJ grew up in a large blended family. His mother, Kim Zolciak, had two daughters, Brielle and Ariana, before her relationship with Kroy. Kroy later legally adopted those two girls. Kim and Kroy then had four biological children together: KJ, Kash, Kaia and Kane.
His childhood was unusual because much of it was documented on television. Viewers first encountered KJ through his mother’s reality-TV career and later saw him as part of the family cast on Don’t Be Tardy. That exposure explains why searches about him often connect his name with both Kim Zolciak and Kroy Biermann.
Career Path
KJ does not have a conventional professional career because he is still a teenager. His documented public activities have included reality-TV appearances and youth football rather than a full-time entertainment or sports career.
Bravo has reported that KJ became a high-school football player and was recognized as a defensive lineman during his freshman season. Current MaxPreps information lists him on Cambridge High School’s varsity roster as a defensive end.
Age
KJ Biermann is 15 years old as of September 12, 2026. Public sources agree on his 2011 birth year, although they disagree about whether his birthday is May 30 or May 31.
Religion
KJ Biermann’s personal religion has not been reliably verified through an authoritative biography, interview or official statement. Any website assigning him a specific religion without a clear primary source should therefore be treated cautiously. His religion is unconfirmed.
Spouse/Partner
KJ Biermann is 15 and there is no verified public information establishing a spouse or confirmed romantic partner. Because he is a minor, unverified relationship claims should not be treated as biographical facts.
Net Worth
There is no reliable public figure for KJ Biermann’s personal net worth. Online estimates would be especially unreliable because he is a minor without a documented independent professional income stream. His net worth is unconfirmed.
Parents
KJ’s parents are Kim Zolciak and Kroy Biermann. Kim is known for The Real Housewives of Atlanta and related reality programming, while Kroy played professional football for the Atlanta Falcons. The couple married in November 2011 and later became parents to four children together.
Height
Current MaxPreps information lists KJ at 6 feet 3 inches and 240 pounds as a Cambridge High School defensive end. A 2025 Bravo report quoted his mother saying he was 6 feet 1 inch at age 13, showing that his height has changed as he has grown. The current 6-foot-3 figure is therefore best treated as a school-sports listing rather than a permanently verified measurement.
Education
KJ is a high-school student. Public school-sports information identifies him with Cambridge High School in Milton, Georgia, and lists him as a sophomore in the 2026-27 football season.
Hometown/State of Origin
KJ’s family has deep public ties to the Atlanta, Georgia, area. IMDb lists Atlanta, Georgia, as his birthplace, while current school records place him at Cambridge High School in Milton, Georgia. Because published birth records conflict on the exact date, the safest description is that he is an Atlanta-area Georgia native.
Official Social Media
No verified official public social-media account belonging directly to KJ Biermann could be reliably confirmed during this research. Recent reporting says his current court conditions restrict phone use and social-media posting, so unofficial accounts or fan pages should not be presented as his official profile.
Verification note:
KJ’s religion, personal net worth, spouse or partner, and official social-media account remain unconfirmed. His exact birth date also has conflicting published records.
