MAFS star Lauren Dunn hits back as her ex Jono McCullough accuses her of having a secret ‘partner’ during their on-screen marriage

Married At First Sight’s Lauren Dunn has hit back after her ex Jono McCullough accused her of having a partner during filming.

The PR expert, 32, and health company owner, 39, were linked in the dating experiment, but their rocky romance came to a tense end before Final Vows.

Lauren was furious to learn that Jono had secretly texted her fellow bride Ellie Dix, who had been with Ben Walters before leaving the experiment.

Jono has since started a relationship with Ellie and used their joint TikTok account to make a series of surprising claims about his on-screen ‘marriage’ to Lauren.

He shockingly claimed that Lauren told him she had a secret ‘partner’ outside of the dating experiment, claims that Lauren has adamantly denied.

“She had someone she was interested in, and she was kind enough to tell me on the first day of the honeymoon,” Jono claimed. ‘She said, “Hey, I have someone out there, I’m not interested in a relationship, let’s just take care of each other and have fun.”

‘She said I cheated on her and clearly that didn’t happen. She had someone else outside the experiment,” he added of his texting scandal with 32-year-old nurse Ellie.

Jono further claimed that Lauren broke down in tears at the last dinner because their co-star confronted her about the claims, not because of him and Ellie.

He said: ‘At the last dinner she did cry because the table tore shreds through her.

“They said, ‘how dare you call Jono a cheater when you had a boyfriend the whole time,’ and she did get upset, but guys, it wasn’t because of Ellie and me.”

Lauren has previously strongly denied she had a ‘secret boyfriend’ during filming, and has hit back again after Jono’s comments.

Her representative told me Yahoo: ‘She has really moved on with her life and hopes that Jono can do the same.’

An insider previously said Lauren was ‘in over her head’ with a mystery man she met while filming in Bali, but she has firmly denied the claims.

‘It’s just a bit ridiculous. I didn’t have a Bali boyfriend,” she told Ny Breaking Australia as she set the record straight.

‘I told Jono at the beginning of the experiment. We talked about our previous dates and who we had been with. I said I had a holiday feeling before the show.

‘I feel like my honesty about that blew up in my face later. It’s almost being used against me.’
