Brielle Biermann: The Oldest Daughter
Brielle Karenna Biermann was born on February 25, 1997. She is Kim’s eldest child from a previous relationship. Her biological father’s identity has never been publicly confirmed. Kroy Biermann legally adopted her in 2013 after marrying Kim.
Brielle has long been a familiar face on Bravo. She appeared alongside her mother from the early seasons of RHOA and throughout Don’t Be Tardy. Now 29, she works as an influencer and content creator. In recent years she got engaged to minor-league baseball player Billy Seidl and has been planning their wedding. Brielle remains close with her mom and has spoken supportively about family challenges.
Ariana Biermann: Building Her Own Spotlight
Ariana Lenee Biermann was born on October 17, 2001. Her biological father is Daniel Toce, Kim’s ex-husband from a short marriage in the early 2000s. Like her older sister, Ariana was adopted by Kroy Biermann in 2013 and took his last name.
Ariana, now 24, has stepped further into the spotlight on her own. She appears on Bravo’s Next Gen NYC, where she has discussed family dynamics and her move to New York City. She also maintains a strong social media presence as an influencer. Viewers have watched her navigate young adulthood, relationships, and independence while still connected to her reality-TV roots.
Kaia Biermann: The Youngest Daughter
Kaia Rose Biermann is the youngest of Kim’s daughters and one of the twins born on November 24, 2013. She shares her birthday with her twin brother Kane. Kaia is Kim and Kroy’s only biological daughter together. At 12 years old in 2026, she has largely stayed out of the heavier media spotlight compared with her older sisters.
Kaia has appeared in family scenes on Don’t Be Tardy over the years but maintains a more private profile as a pre-teen. She is part of the younger group of siblings still navigating school and everyday life amid the family’s ongoing personal changes.
