The affair will play out in upcoming scenes

The 33-year-old supposedly had an affair with co-star Orson Nurse, 41, behind his wife Richelle’s back in scenes set to air this week.

The Sun first reported last week how Richelle had let slip about something which happened that had left her furious.

She accused Orson of trying to recouple with another bride, telling fans: “People will see the truth. It’s a waiting game.”

At the end of last night’s episode, it was revealed that Hannah tried to get Orson to hold her hand.

Now a TV source has told MailOnline: “Hannah and Orson’s betrayal is revealed during one of the commitment ceremonies after Sascha blurted out the truth behind their closeness.

“Their affair rocks the cast who have all been trying to navigate their marriages with advice from the relationship experts and the last thing you expect is for two couples to break their vows.

“It causes uproar and confusion, especially for Richelle, who hoped she could progress in her romance with Orson.

“As for Stephen, he sees Hannah cheating as an excuse to pursue another bride and he ups the ante with Sionainn despite the fact she’s married to Ryan.”

It comes after Richelle claimed last week that scenes had been ‘edited out’ and that viewers were not getting the full story.

One viewer asked: “Is there something we aren’t seeing between Richelle and Orson?”

Richelle replied: “Yes there’s a lot you’re not seeing behind tonight and previous edit that I will address to comments on this post…tomorrow!”

Stephen and Hannah struggled to see eye to eye from the start, with Stephen reportedly trying to quit the process.

Married At First Sight have not commented on the situation.
