Brielle Biermann is preparing to marry fiancé Billy Seidl, but one important family member reportedly won’t be there to celebrate: her adoptive father, Kroy Biermann.
According to a new report from Page Six, the 29-year-old daughter of Real Housewives of Atlanta alum Kim Zolciak has decided not to include Kroy in her upcoming November wedding, marking another painful development in the family’s ongoing estrangement.
And the situation appears to be so strained that Kroy reportedly doesn’t even know the details of his daughter’s big day.
“Kroy has zero idea about the wedding,” a source told Page Six.
“He has no clue about any details. Brielle does not want him there.”
The insider also claimed that Kroy hasn’t made any effort to find out whether he will be attending.
“He has not tried reaching out about going, either,” the source revealed.
TMZ separately reported that Kroy never received an invitation to Brielle’s wedding and that their strained relationship has reached the point where he will not be included in the celebration.
The news comes just weeks before Brielle is expected to exchange vows with Billy, a minor league baseball player she began dating in 2023.
The couple announced their engagement in February 2024 after Billy proposed with a diamond ring.
Despite the ongoing turmoil within the Biermann family, Brielle has remained focused on moving forward with her wedding plans.
In August, she celebrated her bachelorette party in Turks and Caicos with friends, sharing photos from the tropical getaway as she prepared for married life.
However, the absence of Kroy from the guest list is especially significant considering the role he once played in Brielle’s upbringing.
Although Kroy is not Brielle’s biological father, he became a father figure to her after beginning his relationship with Kim.
The former NFL player married Kim in November 2011, and in 2013, he legally adopted both Brielle and her younger sister, Ariana Biermann.
At the time, the adoption was a major milestone for the family, with Brielle and Ariana taking Kroy’s last name.
Their close-knit family dynamic was frequently documented on Bravo’s Don’t Be Tardy, where viewers watched Kroy take on a parental role while helping raise Kim’s daughters and their four younger children.
For years, Kroy appeared to have a strong bond with Brielle and Ariana.
But that relationship has reportedly deteriorated significantly amid his bitter divorce from Kim.
The couple’s marriage began unraveling publicly in May 2023, when both filed for divorce following more than a decade together.
Although they briefly attempted to reconcile and withdrew their initial divorce filings, Kroy filed again in August 2023, stating that the marriage was irretrievably broken.
Their separation has since become an increasingly contentious legal battle involving finances, property and custody of their four younger children.
Throughout the proceedings, Brielle and Ariana have publicly expressed frustration over the situation and the impact it has had on their family.
In July 2026, Brielle admitted that she and Kroy were barely communicating when asked whether he would attend her wedding.
“I haven’t really spoken to Kroy,” she told TMZ.
“It’s in the air, ever changing.”
At the time, Brielle hadn’t completely ruled out the possibility that Kroy could be part of the celebration.
However, she suggested that their relationship had become increasingly difficult to navigate.
She also expressed frustration with Kroy’s handling of certain matters involving Kim, indicating that their disagreements extended beyond the divorce itself.
Now, months later, sources claim Brielle has made her decision and does not want him at the wedding.
Her sister Ariana has also spoken candidly about the family’s strained relationship with Kroy.
During a July interview with Us Weekly, the Next Gen NYC star admitted that the possibility of Kroy missing Brielle’s wedding was upsetting.
“I think it’s really sad,” Ariana said.
“I’m sad that it all got to this point.”
Ariana explained that the situation was especially heartbreaking because she and Brielle had once shared a close relationship with their adoptive father.
She suggested that the sisters had made efforts to maintain a connection with Kroy despite the ongoing problems between him and Kim.
However, Ariana later revealed that she and Kroy were no longer speaking.
During a separate interview with TMZ, Ariana explained that she and Brielle had tried to preserve their relationship with Kroy independently of their parents’ divorce but eventually reached a point where it was no longer working.
The strained family dynamic has also unfolded during a difficult period for Kim and Kroy’s four younger children.
In recent months, the family has faced additional legal challenges involving their teenage son, KJ Biermann, who was arrested in August 2026.
KJ has pleaded not guilty to multiple felony charges involving alleged sexual offenses, and his case remains ongoing.
The teenager was released on bond under court-ordered restrictions.
While those allegations are separate from Brielle’s wedding plans, the situation has added another layer of public scrutiny to an already complicated family period.
Despite the ongoing issues, Brielle has continued preparing for her November wedding.
Sources previously told Page Six that the celebration would move forward as planned, even with the various challenges affecting her family.
Brielle has kept many details about the ceremony private, including the exact date and guest list.
She has, however, shared glimpses of her wedding preparations and her excitement about marrying Billy.
The former Don’t Be Tardy star has also developed a close relationship with Billy’s family, previously sharing moments from wedding planning with his mother.
But while Brielle is preparing for a new chapter with her fiancé, the reported decision to exclude Kroy represents a significant change from the family relationships viewers once watched on Bravo.
The same man who legally adopted Brielle and helped raise her is now reportedly being left out of one of the biggest days of her life.
As of the latest reports, neither Brielle nor Kroy has publicly confirmed the alleged wedding guest-list decision directly.
Kroy has also not publicly responded to the new claims about his absence.
