The Zolciak-Biermann family is BACK for a new season of Don’t Be Tardy…
The Biermann family.
The former Real Housewives of Atlanta star met her husband, Kroy Biermann, while she was starring in the Bravo series. At the time, she was a single mom to daughters Brielle and Ariana. The reality star and NFL linebacker got married on Nov. 11, 2011, and have since welcomed four children together: Kroy Jr., Kash and twins Kaia and Kane.
Kroy filed to adopt Kim’s two daughters shortly after they wed. In July 2013, Brielle and Ariana legally changed their last names when the adoption became final.
In April 2023, after roughly 12 years of marriage, Kim and Kroy filed for divorce. However, in July 2023, a source told PEOPLE that the couple called off the divorce and are “trying to make it work for the kids.”
Then, in August 2023, Kroy filed for divorce for a second time. Years later, their divorce is still not finalized.

Brielle was born on Feb. 25, 1997, and is the eldest of Kim’s children. In 2013, she was adopted by Kroy along with her sister Ariana.
Brielle launched KAB Cosmetics in 2019 with Kim and Ariana. In addition to modeling for their makeup line, she often poses for photos while wearing bikinis from Kim’s swimwear line, Salty K.
Despite being in front of cameras for much of her adult life, it still hasn’t been easy to hear criticism from others about her appearance.
“Well they think that you have a lot of plastic surgery growing up on TV,” she said during an appearance on Watch What Happens Live with Andy Cohen. “They don’t realize that you look different when you’re 10 years old to 24. I hope I look f---ing different.”

In August 2021, the then-24-year-old underwent double jaw surgery to correct her “tmj & 9 mm overjet overbite.” She insisted it was “NOT for aesthetics but for quality of life.”
“I sucked my thumb til i was 9 ishhh which made the roof of my mouth suuuuuper narrow and my excessive overbite cause my teeth to have no contact whatsoever,” she wrote on Instagram following the surgery.
Brielle is engaged to minor league baseball player Billy Seidl. The pair shared the big news on Instagram in February 2024.
Ariana Lenee Biermann, 24

Kim welcomed her second daughter, Ariana, on Oct. 17, 2001, with then-husband Daniel Toce, to whom she was married from 2001 until 2003.
Ariana spent much of her early years in front of the camera while appearing on Real Housewives of Atlanta and the Biermann’s spinoff series, Don’t Be Tardy. She later opened up about growing up in the spotlight, sharing that she struggled with her body image and faced bullying at school.
On Aug. 13, 2022, Ariana was arrested on suspicion of driving under the influence of alcohol while in the car with her on-again, off-again high school boyfriend. She was charged with three misdemeanors: driving under the influence of alcohol, improper/erratic lane change and underage possession/purchase of alcohol.

Her mother came to her defense in a statement posted on her Instagram Stories that read: “Ariana was involved in a minor fender bender. When police arrived on the scene, the investigating officer immediately initiated an investigation for DUI of alcohol. Despite Ariana’s constant invocation that she was upset and anxious from the minor accident, the officer incorrectly concluded she was impaired. That was not the case.”
A few months later, Ariana celebrated her 21st birthday with a cake that featured a photo of her mugshot.
Kim also marked the milestone birthday with a message on Instagram. “Happy 21st Birthday to my sweet @arianabiermann. Your generous heart, giving nature, commitment to your family & friends, the love you spread daily and the passion you have for life (and pastels) never goes unnoticed! Thank you for being YOU!!!! You are such a bright light in this world,” she wrote.
Ariana started starring in Next Gen NYC in June 2025.

Kim and Kroy welcomed their first child together, Kroy Jr. (nicknamed KJ), on May 31, 2011.
While speaking at a BravoCon panel in 2019, Kim opened up about KJ being the target of bullying at school.
On Sept. 3, 2026, KJ was indicted on seven felony charges of aggravated child molestation, aggravated sexual battery, aggravated sodomy, false imprisonment and three counts of sexual battery against a child under the age of 16.
The charges stem from an alleged incident that took place on April 23, which led to KJ’s arrest on Aug. 17. He is scheduled to appear in court on Sept. 9.
“The allegations being made against my son are nothing short of reckless and deeply troubling. He categorically denies ever being involved with this woman or engaging in the conduct she has alleged,” Kim said in a statement issued to Us Weekly following KJ’s arrest.
Kash Kade Biermann, 14

Kim and Kroy’s second son, Kash, was born on Aug. 15, 2012.
In April 2017, then-4-year-old Kash was mauled in the face by the family’s dog, nearly blinding him with a significant scratch just one millimeter away from his left eye. With the help of doctors, he “healed up incredibly“ with no damage to his vision.
Despite the attack, the “animal lover“ was comfortable cuddling with a new puppy just months after the incident. He also reunited with his dog Sinn, who had bitten him. The decision to keep Sinn was not one taken lightly by the family, as Kim and Kroy told PEOPLE.
“I hated Sinn,” Kroy said. “I genuinely felt a deep rage for what he had done to my son. Sinn was always a good dog, extremely obedient and protective and not at all aggressive. He’s hyper-active and hyper-sensitive but wants to work and loves to be commanded. I love my dog, and nothing like this had ever happened to me before. But it’s my son. I don’t love anything more than my flesh and blood. I thought, ‘I don’t want to see the dog — he doesn’t get a second chance.’”
Kim added, “Sinn and Kash have been best friends since the day we got Sinn ... Kash is an absolute animal lover, and Sinn is definitely his favorite, without a shadow of a doubt. That’s why it was extra hard.”
Kash underwent reconstructive face surgery in November 2020 to further “correct the injury.” Despite it being over three years since the incident, Kim explained that she and her husband still had a difficult time coping during their son’s recovery process.
“We had a rough couple days. Kroy and I cried many many times along side Kash. We sat in the plastic surgeons parking lot (only one parent could go in and I knew Kroy could handle it better than me) but when Kash/Kroy came out and sat in the backseat with Kash on his lap and tears streamed down both their faces, I could barely breathe,” she wrote on Instagram. “My heart was broken that we even had to go through all this again.”
Kaia Rose & Kane Ren Biermann, 12

The former Real Housewives of Atlanta star welcomed twins on Nov. 24, 2013, after announcing her pregnancy in August 2013. Kaia was the smaller of the two at birth, but arrived 31 minutes ahead of her brother Kane.
Shortly after announcing the twins’ birth, Kim explained the meaning behind their middle names on Instagram. Rose, Kaia’s middle name, is after Kim’s psychic, whom the reality star said “is like a grandma to me and been a huge part of my life for 13 plus yrs.” Ren, Kane’s middle name, is after the “OBGYN who has delivered 5 of the 6 kiddos, who has also been a big part of my life for 12 yrs and we simply adore him.”
Even with a large age gap between Kaia and her older sisters, she’s already following in their footsteps (and mimicking them) in the glam department.
“I think Kaia took all sassiness and style icon queen from me and my mom and my sister,” Brielle shared with PEOPLE. “She is going to be a model or a fashion stylist or a makeup owner. She is all about her clothes, especially her headband. She wears a headband every night when she goes to bed.”
Kim has said her youngest son is “built exactly like Kroy,” but has her “face/ hair texture/smile.”
“Extremely easy baby thank God because his twin was very demanding,” she wrote of Kane on Instagram. “He is extremely extremely smart. Mind blowing smart! Very honest.”
