Jon Gosselin made shock cheating claims against his ex-wife Kate Gosselin Wednesday, with his son Collin backing up his account.

The 48-year-old reality television star suggested that the bond between his ex-wife Kate, now 50, and her former bodyguard, Steve Neild, aged 50, evolved from a professional association to a romantic one. This shift reportedly marked the end of their marriage during their peak time in reality TV.

Jon posted on Instagram, sharing a picture of Kate with Neild, alongside a link to a Page Six article about their current dating situation, hinting that it’s more of a relationship revival.

‘Guess who really ruined the marriage,’ Jon said. ‘Read for yourself.’

The reality star from Wyomissing, Pennsylvania, expressed that previously, when he made similar allegations, they were dismissed, though now they seem validated: ‘Perhaps now when I speak, people will pay attention!!!’

The Daily Mail has reached out to reps for Kate for comment on the story.

Jon and Kate’s son Collin, 21, backed up Jon’s account in a post on Instagram Stories Wednesday.

‘What truly bothers me,’ he revealed, ‘is that my mom had been involved with our bodyguard back in 2009, and frequently shared hotel rooms with him during our family vacations, while I stayed in a nearby room!’

Collin added: ‘Now everyone thinks her being with him is some cute novel romance.

‘By the way my dad received death threats and got shunned by the public for years for “having an affair” and “leaving his kids.”‘

Collin later clarified on Instagram Stories that his intention wasn’t to create controversy but to clarify any public misunderstandings regarding the family’s situation. (Jon refuted any accusations that he was unfaithful in the marriage.)

‘Drama isn’t something I engage in, and I’m occupied with college, work, and managing my business, so don’t think I thrive on this,’ Collin stated. ‘However, I have strong feelings about cheating and placing blame on others for one’s own actions.’

‘Everyone says my dad and I are hung up on my mom. We are not. We have suffered the damage of a narcissist and cried together. 

Collin concluded in saying, ‘So no we won’t just go and make TikTok’s and act reformed when we still feel pain from our past.’

The former couple and their family were a TV sensation with the popularity of their 2007–2009 series, Jon & Kate Plus 8.

They had wed in 1999 and welcomed twins Madelyn and Cara, then sextuplets Aaden, Hannah, Leah, Alexis, Collin and Joel, who as result of In vitro fertilization. Their divorce was finalized in 2009.

In the wake of the divorce, TLC recast the show as Kate +8, and six more seasons aired before it ended in 2017. 

Jon said in a 2025 interview with E News! that he hadn’t spoken with his ex-wife Kate in around seven years.

‘We don’t communicate,’ he said. ‘I think the last time I heard her voice in person was, like, 2018.’

Last month, Kate shared sentiments on parenting in a TikTok post, saying, ‘I don’t know if you have kids or don’t have kids, but I just, I made decisions based on how I would want to be treated, honestly.

‘And I didn’t buy into all the drama and the hate, and the ugly. And I had kids involved, so I wanted it to be as peaceful for them as I possibly could.’
