Watch the moment JJ’s ‘affair’ with Ella exposed tonight – as Bianca runs out in tears and Nathanial’s left fuming

MARRIED At First Sight star JJ's 'affair' with Ella is exposed tonight.

Last week the pair admitted that they both fancied each other while they went for drinks with their other co-stars.

Ella tied the knot with Nathaniel as part of the social experiment, however it's not been plane sailing for them both.

Meanwhile JJ and Bianca entered much later - but JJ has made it clear that he doesn't fancy his wife.

During Wednesday's instalment of the E4 programme, the two met up behind Nathaniel and Bianca's back, and today the rest of the cast find out about what they've been up to.

Tonight the situation gets very heated when Nathaniel brings it up at the dinner ceremony.

Nathaniel asks: "Is it reciprocated with Ella?"

JJ replies: "Ella is my type."

"She wants to be with you... is it reciprocated? That's all I wanted to know," Nathaniel asks him.

JJ says: "The conversation is between Bianca and I, not you, for one."

He adds: "I have a connection with Ella. That's what I'm telling you. I don't have to tell you anything mate.

"As a man to man there is a connection with Ella.

"There is definitely something genuine there, I don't know what is going to happen next.

"Simple as that.

"I'd like to have this conversation with you one on one but this conversation doesn't allow that."

Ella then jumps into the conversation.

She says: "You have made it clear to everyone...

"Everyone around this table knows - guys does he fancy me?

"Yes or no. Everyone knows you don't fancy me. You've made zero effort."

But Nathaniel has none of it and says: "I changed my whole being."

The camera then pans in on JJ and wife Bianca talking.

Bianca asks her husband: "How have you got a connection with her?!"

She adds: "You're just a f***ing liar. You're a liar."

Nathaniel and Ella start arguing again and Bianca asks what has happened with Ella.

"Nothing has happened," he reassures his wife.

"You're telling me that you two like...," Bianca replies.

As Bianca gets up she says: "I am so f***ing confused.

"I'm going to take five."

Laura stands up and says: "Guys I don't care what is going on but there is a girl crying."

What will happen next?
