Kroy “KJ” Biermann Jr. is an American media personality and high school athlete best known as the eldest biological son of former NFL player Kroy Biermann and television personality Kim Zolciak. Born on May 31, 2011, KJ was introduced to the public from an early age because of his parents’ prominent careers in professional football and reality television.
KJ grew up in Georgia alongside his younger siblings, Kash, Kaia, and Kane. He also grew up alongside his older half-sisters, Brielle and Ariana, whom Kroy later adopted. His childhood was closely connected to his parents’ reality television careers, and many aspects of his early family life were documented for television audiences.
Born during Kim Zolciak’s time on The Real Housewives of Atlanta, KJ appeared on television from infancy. He later became a regular presence on the family’s Bravo spin-off, Don’t Be Tardy, which followed the Biermann-Zolciak household and aired for eight seasons. Growing up in front of cameras gave KJ a public profile from childhood, although much of his early life remained centered on his family and upbringing in Georgia.

As the couple’s first biological child together, KJ became part of the family’s public story from an early age.

Kroy Jagger Biermann Jr. Education
Kroy “KJ” Biermann Jr. attended Cambridge High School in Milton, Georgia, where he continued his education while also developing an interest in athletics. His time at the school was notable for his involvement in football, following in the athletic background of his father, former NFL defensive end Kroy Biermann. KJ competed as a defensive lineman, combining his academic responsibilities with participation in high school sports.
As a student-athlete, KJ’s football activities became part of his public profile. Playing on the defensive line required physical strength, discipline, teamwork, and commitment, while his school environment provided an opportunity to pursue his education away from the cameras that had been part of his childhood. His participation in high school football also reflected his continued connection to the sport through his father’s professional football career.
In September 2026, KJ’s educational arrangements changed following a court order connected to his pending legal case. As part of his bond conditions, he was required to transition to virtual schooling from home rather than continue attending classes in person. His current educational status is therefore centered on online learning while the legal proceedings remain ongoing.
Kroy Jagger Biermann Jr. Career
Kroy “KJ” Biermann Jr.’s public career began in reality television rather than through a conventional professional occupation. Born into a family already featured on Bravo, he appeared on The Real Housewives of Atlanta from a young age. His early television appearances introduced him to audiences as one of Kim Zolciak and Kroy Biermann’s children and made him a familiar face to viewers of the show.
KJ later became a recurring presence on Don’t Be Tardy, the Biermann-Zolciak family’s reality television spin-off. The series documented the family’s daily life, relationships, celebrations, and major milestones, allowing viewers to watch KJ grow from childhood into his teenage years. His appearances on the program contributed significantly to his recognition as a young media personality.
Outside television, football has been an important part of KJ’s development and public profile. He attended Cambridge High School in Milton, Georgia, where he competed as a defensive lineman. His involvement in high school football reflected his connection to the sport through his father, Kroy Biermann, who enjoyed a professional NFL career with the Atlanta Falcons and later the Buffalo Bills.
As a teenager, KJ’s activities have remained primarily focused on education, family life, and high school athletics rather than an established professional career. Unlike his parents, he has not yet developed a long-term career in entertainment or professional sports. His early exposure to reality television, however, has given him experience with public appearances and life in front of an audience.
In 2026, KJ’s public profile became increasingly associated with legal developments rather than entertainment or football. Following his August 2026 arrest and subsequent indictment on serious felony allegations, his educational and personal activities were affected by court-ordered restrictions, including a transition to virtual schooling. The case remains pending, and the allegations should not be treated as established facts or a criminal conviction.
Kroy Jagger Biermann Jr. 2026 Legal Case and Arrest
Kroy “KJ” Biermann Jr. became the subject of significant media attention in 2026 following his arrest in Alpharetta, Georgia, in connection with allegations arising from an incident reportedly involving a local fitness facility in April 2026. The case attracted widespread attention because KJ was only 15 years old at the time and is the son of two well-known reality television personalities, Kim Zolciak and former NFL player Kroy Biermann.
On September 3, 2026, a Fulton County grand jury reportedly indicted KJ on seven felony counts, including aggravated sodomy, aggravated sexual battery, aggravated child molestation, and false imprisonment. Because of the seriousness of the allegations and the circumstances surrounding his age, the case has received substantial coverage. The legal proceedings remain active, and the charges represent allegations rather than findings of guilt.
KJ’s defense team and family have strongly denied the allegations and maintained that he is innocent. His attorneys have reportedly pointed to what they describe as the absence of physical DNA evidence and a polygraph examination that KJ passed. These claims form part of the defense position and have not themselves determined the outcome of the criminal proceedings.
On September 11, 2026, a judge granted KJ bond following a hearing concerning his detention. The reported conditions included electronic ankle monitoring and a requirement to attend school virtually from home, along with other restrictions connected to the pending case. These conditions have significantly altered his day-to-day life and educational arrangements.
The legal case has also brought renewed public attention to KJ’s family and his upbringing in the reality-TV spotlight. Despite the heightened media interest, KJ remains legally presumed innocent unless and until proven guilty in court. His case is ongoing, and any future developments will depend on the judicial proceedings and decisions made by the court.
Kroy Jagger Biermann Jr. Personal Life and Family
Kroy “KJ” Biermann Jr. comes from the well-known Biermann-Zolciak family and is the eldest biological child of former NFL player Kroy Biermann and reality television personality Kim Zolciak. His parents married in November 2011, shortly after his birth, and went on to have three more children together: Kash Biermann and twins Kaia and Kane Biermann. KJ therefore grew up as part of a large blended family that has been publicly documented for more than a decade.
KJ also has two older half-sisters, Brielle Biermann and Ariana Biermann, from Kim Zolciak’s previous relationships. Kroy legally adopted both girls in 2013, after which they took the Biermann surname. Brielle, the eldest of the siblings, has maintained a public career as an influencer and is engaged to professional baseball player Billy Seidl. Ariana has likewise remained in the public eye through social media and reality television.
KJ’s family life has been shaped by both his parents’ celebrity careers and their highly publicized marital difficulties. Kim and Kroy began divorce proceedings in 2023, and their separation has involved continuing disputes concerning their children and custody arrangements. In September 2026, Kim and Brielle were also seen supporting KJ at a court hearing related to his pending criminal case. KJ is not publicly known to have a wife or fiancé, and his personal life outside his family and school activities has largely remained private.

As for his nationality, he is American, having been born and raised in the United States. His family has longstanding ties to the Atlanta, Georgia, area.
KJ has a notably tall and athletic build, which is particularly evident from his involvement in high-school football.

KJ’s future legacy remains difficult to define because his life is still developing. The legal proceedings that began in 2026 have become a major part of his current public profile, but the allegations remain unresolved and should not be treated as established facts.
