Kaia Biermann is the 12-year-old daughter of reality TV personality Kim Zolciak-Biermann and former NFL player Kroy Biermann. She is also the twin sister of Kane Biermann and one of six children in the family. Unlike her older sisters, Brielle and Ariana, Kaia has largely stayed out of the spotlight as she has grown up.
Kaia first appeared on television as a baby on her family’s Bravo reality series Don’t Be Tardy. Today, she is a middle-school student living in Atlanta with her mother, according to Bravo’s current family profile.
How Old Is Kaia Biermann?
Kaia Biermann is 12 years old in 2026. She was born on November 24, 2013.
She shares her birthday with her twin brother, Kane. The twins are the youngest of Kim Zolciak-Biermann and Kroy Biermann’s four biological children.
Kaia and Kane are also considerably younger than their sisters Brielle and Ariana and their brothers KJ and Kash.
Who Are Kaia Biermann’s Parents?
Kaia’s parents are Kim Zolciak-Biermann and Kroy Biermann.
Kim became known through The Real Housewives of Atlanta, where she was an original cast member, while Kroy played professional football, primarily for the Atlanta Falcons.
The couple married in November 2011 and later had four children together: Kroy Jr. (KJ), Kash, Kaia and Kane. Kroy also legally adopted Kim’s daughters Brielle and Ariana in 2013.
Kim and Kroy’s marriage has since gone through a highly publicized divorce process. Kroy filed for divorce for a second time in August 2023, and the divorce remained unresolved as of PEOPLE’s September 2026 family update.
Who is Kaia Biermann’s Twin Brother?
Kaia’s twin brother is Kane Biermann.
The twins were born on November 24, 2013, and are the youngest children in the family. Bravo currently lists both Kaia and Kane as middle-school students and says the twins have remained largely outside the public spotlight compared with their older siblings.
Their childhood was nevertheless documented on Don’t Be Tardy. The twins joined the show during its third season when they were infants and appeared through the show’s eighth season.
Who Are Kaia Biermann’s Siblings?
Kaia is part of a six-child family.
Her siblings are:
- Brielle Biermann — Kim’s eldest daughter
- Ariana Biermann — Kim’s second daughter
- Kroy “KJ” Biermann Jr. — Kaia’s older brother
- Kash Biermann — Kaia’s older brother
- Kane Biermann — Kaia’s twin brother
Brielle and Ariana are Kim’s daughters from earlier relationships and were legally adopted by Kroy in 2013. KJ, Kash, Kaia and Kane are Kim and Kroy’s biological children.
Did Kaia Biermann Appear on Don’t Be Tardy?
Yes. Kaia appeared on Don’t Be Tardy as part of the Biermann family.
The Bravo series followed Kim, Kroy and their children from 2012 through 2020. Kaia and Kane were introduced to viewers when they were babies and remained part of the family story as they grew up.
Her television exposure came from being part of the family rather than from having her own entertainment career.
That distinction is important because Kaia’s public profile is very different from that of Brielle and Ariana, who have developed careers and large social-media followings of their own.
What Does Kaia Biermann Do Now?
Kaia is currently a student and has not established a separate public career.
Bravo’s July 2026 profile lists Kaia and Kane as middle-school students and says the twins live with Kim in Atlanta. The same profile notes that they have remained largely out of the spotlight while their older siblings have pursued more public careers.
There is therefore limited verified information about Kaia’s day-to-day life, interests or future career plans.
Because she is still a minor, that relative privacy also separates her from the extensive public coverage surrounding her adult siblings.
Why is Kaia Biermann Popular in 2026?
Kaia’s name has appeared more frequently in recent family coverage because of developments involving the Biermann family.
In September 2026, Kim and Kroy’s 15-year-old son KJ faced felony charges stemming from allegations involving a female classmate. Prosecutors also raised additional allegations in court involving a minor family member. KJ’s attorney has denied the allegations and said he is innocent.
Kaia is not accused of wrongdoing in these reports. Her name appears because she is one of KJ’s siblings and because news coverage has been providing background on Kim and Kroy’s six children.
That distinction matters when reading headlines about the family: current legal reporting concerns KJ, not Kaia.
How is Kaia Biermann Different from Brielle and Ariana?
The biggest difference is the level of public exposure.
Brielle and Ariana are adults who have developed their own public careers. Brielle has worked as an influencer and has been involved with KAB Cosmetics, while Ariana has appeared on Next Gen NYC and lives in New York City.
Kaia has followed a different path so far.
She grew up on television because of her family’s reality show, but she has not turned that exposure into a separate entertainment or influencer career. Bravo specifically describes Kaia and Kane as remaining largely out of the spotlight.
What is Known About Kaia Biermann’s Life Outside Reality TV?
There is relatively little reliable public information about Kaia’s private life, and that is partly the point of her current profile.
She is a middle-school student, a twin, one of six Biermann children and the daughter of two highly recognizable reality-TV figures. Beyond those facts, most of the family’s recent media attention has centered on Kim and Kroy’s divorce, their older children and the legal issues involving KJ.
For people looking up who Kaia Biermann is, the clearest picture is therefore fairly simple: she is Kim Zolciak-Biermann and Kroy Biermann’s youngest daughter, Kane’s twin, and a former Don’t Be Tardy child cast member who has so far maintained a much quieter public life than her older siblings.
