Following their Talking Married appearance, where Dan stressed he couldn't trust a cheater, a woman has come forward about his infidelity - while he was still with Jess.
Watch the shocking caller tell Kyle and Jackie O about how and when they cheated.
None more than Dan, who condemned his partner's flirtatious behaviour.
Kyle and Jackie O received a message on Instagram from a listener, Hannah.
She claimed that Dan had “100%” cheated on Jess after he came onto her in a bar two months ago.
And MAFS bride confronted her on Instagram.

“Can I just ask, when did you receive this message?” Jackie asked about Jess' message
“Yesterday morning,” Hannah said.
“Okay so I’ll read out the message,” Jackie said. “Obviously she’s worried that you and Dan have hooked up.
“She says, ‘Hey babe, sorry to message you but I’m an absolute emotional wreck right now. Can you please tell me what happened with Dan? I’ve just been through so much I feel like maybe this will help me move on.
“This isn’t the first cheating allegation I’ve suffered either. It’s just so heartbreaking I’ve moved my entire life here. He said he has never seen you in his life but my gut just doesn’t believe it.’”

“I just told her straight out exactly what had happened,” Hannah said.
“This was like two months ago… He was trying to do that and I said no and then he literally kissed me,” she claimed.
Dan’s friends told her he was on Married At First Sight, but at this point, he wasn't on the show.
Then in a shock twist, a listener called Zoe told the show, “She did the same thing to Dan,” explaining, “She actually hooked up with Eden [from Love Island] after the first episode aired to TV.
“What actually happened was that he had DM’d her after the first episode had aired and she was like, ‘Yep, come to the GC’, and then they f***ed,” Zoe said.
“So then she would have been with Dan when that first aired,” Jackie said.
One word: DRAMA.
