Kim Zolciak reveals ‘final straw’ in Kroy Biermann breakup, shocking daughter Ariana

Kim Zolciak made a bombshell claim about the end of her marriage to Kroy Biermann over the weekend.

When asked on the BravoCon 2025 red carpet by “Entertainment Tonight” about the “final straw” in the relationship, the “Real Housewives of Atlanta” star didn’t hesitate.

“He cheated, so…” she alleged.

The admission seemingly shocked the Bravolebrity’s daughter Ariana Biermann during their joint interview with the outlet.

The “Next Gen NYC” star, 24, froze before saying, “Holy s–t.”

Reps for Zolciak, Kroy and Ariana did not immediately respond to Page Six’s requests for comment.

While Zolciak did not elaborate further on her accusations on Sunday, she did give an update on where she and her estranged husband stand as their contentious divorce battle rages on.

“I don’t think Kroy will ever give me a divorce,” the “Don’t Be Tardy” alum, 47, said. “No movement, no change. Just constant antics.

“I exhaust myself trying to keep [my kids] in a positive headspace,” she added. “I take on a lot of the financial responsibility. … Co-parenting would just make their lives so much happier, and I just keep continuing to pray for that.”

Zolciak claimed she and Kroy, 40, “can’t get to that place” because he vowed to “publicly destroy” her when she filed for divorce in 2023.

“That’s been his goal, and that’s all he cares about,” she added. “But it hasn’t worked yet.”

The on-again, off-again couple tied the knot in November 2011 and called it quits 12 years later.

In a December 2023 bodycam footage, the retired NFL player accused Zolciak of “f–king other men” — which she later denied in a Celebuzz statement.

“I vehemently deny any allegation that I have been unfaithful to Kroy at any point in our 12-year marriage. Any claim to the contrary is downright false, baseless, and slanderous,” Zolciak wrote, pointing out that her estranged husband was “enraged” when making the claim.

“I have tried not to speak on these hurtful allegations, but I am at a breaking point with this and I will not stay silent when my character is being assassinated,” she continued.

Zolciak has since moved on with Kyle Mowitz, who is currently in the middle of his own divorce from Jillian Green.

Last month, Green told Us Weekly that Biermann reached out to her, predicting his “narcissistic” ex will “drain money from Kyle.”

Zolciak defended her romance with Mowitz at BravoCon, insisting she doesn’t have to “wait until [she’s] legally divorced” to start dating again.
