Kim Zolciak stole the spotlight at BravoCon by dropping a jaw-dropping revelation about the end of her 12-year marriage to Kroy Biermann.

The 48-year-old former star of “Real Housewives of Atlanta” candidly reflected on the tumultuous journey she and Biermann have experienced over recent years.

The couple initially parted ways in May 2023, temporarily halted their divorce proceedings in July, only for Biermann to refile in August. Since then, their relationship has been a dramatic cycle of breakups and reconciliations.

This time, however, Zolciak identified the alleged incident that she believes irreparably damaged their union.

When asked about the ‘final straw’ that ended their marriage, she responded without hesitation.

“He cheated,” she revealed to ET during an interview on the red carpet.

Kim Zolciak lit up BravoCon with a bombshell no one saw coming — finally revealing the moment her 12-year marriage to Kroy Biermann shattered for good

After first splitting in May 2023 , briefly calling off the divorce in July, and then watching Biermann file again that August, the pair have been locked in a bruising, on-again off-again battle ever since; (Kory in 2022)

The Daily Mail has reached out to reps for Biermann for comment and has yet to hear back. 

The accusation stunned the crowd — but no one more than her daughter Ariana, who sat beside her during the interview. 

The 25-year-old was caught completely off-guard, blurting out: ‘Holy s—.’

The pair’s marriage has been rocked by allegation of infidelity on both sides – in December 2023, Biermann accused his estranged wife of ‘f*****g other men’ in police bodycam footage.

Zolciak then issued a statement via a link on her main Instagram page denying these claims.

She expressed:  ‘The comments made in the bodycam footage from Kroy who is obviously enraged are untrue.

‘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.’ 

‘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 emotionally continued. 

Zolciak didn’t hold back as she detailed the chaos of her post-marriage life. 

She called her split from Biermann ‘impossible,’ saying the divorce has drained ‘lots of money’ with ‘no movement’ toward a settlement.

‘There’s no co-parenting, it’s disturbing. If you only knew,’ she said, speaking of the four kids she shares with Biermann: Kroy Jr., 14, Kash, 13, and twins Kaia and Kane, 11. 

‘As much as I would love to share the truth, I won’t, because I have children. You don’t bash the mother of your children. Their stability is in my own.’

In December 2023 bodycam footage, the retired NFL star accused Zolciak of ‘f–king other men’ — a claim she fired back at in a strong statement.

But this time, Zolciak put a name to the betrayal she says broke the marriage beyond repair as  when asked what the ‘final straw’ was, she didn’t flinch

The accusation stunned the crowd — but no one more than her daughter Ariana, who sat beside her during the interview, blurting out: ‘Holy s—‘

‘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, noting that her estranged husband was ‘enraged’ when making the accusation.

‘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 added.

Amid the chaos, Zolciak revealed at BravoCon that she’s found happiness again with Kyle Mowitz, who is also navigating his own divorce from Jillian Green.

‘I’m a Taurus. I’m loyal to a fault. We went on our first date, and we’ve been together ever since,’ she said, insisting they’ve kept things private for ‘several reasons’—mostly because, as she put it, ‘I do like my personal life private, I really do.’

Defending her new relationship, Zolciak said she doesn’t have to ‘wait until [she’s] legally divorced’ to move on. 

She and Mowitz bonded over ‘horrible circumstances’ while both going through divorces for ‘the exact same reason.’

‘I’m happy as hell,’ she told ET. ‘I’m at peace.’ 

And she shot down rumors that her boyfriend’s marital status was an issue.

‘I’m legally married and so is he. So, he’s been going through a divorce for years as well, and so have I. So I don’t know – I’m supposed to wait til I’m legally divorced? I don’t think Kroy will ever give me a divorce.’

Zolciak described the legal battle with Biermann as relentless: ‘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.’

She claimed Kroy, 41, ‘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,’ Kim said. ‘But it hasn’t worked yet.’
