Dean and Davina's secret kiss in MAFS teaser

Married At First Sight looks set to shock tonight, as the show teases that Dean and Davina will kiss behind their respective partner's backs.

Dean, who is 'married' to Tracey, and Davina, who is 'married' to Ryan, hit it off when they met at the group's first dinner party, flirting outrageously over the table.

Now it seems as though the pair have been unable to resist each other, with the clip showing them having a conversation about wanting to pursue each other, followed by flashes of them in what appears to be a steamy clinch.

In the ultimate betrayal, Dean and Davina can't keep their hands off each other and the voiceover promises the week of viewing ahead will be "the biggest week of married drama".

Things start with Davina intent on snagging her man, deceptively telling Tracey that "Dean may not be your perfect person" in a bid to sabotage their relationship.

After lots of steamy lingering glances the pair can be seen sitting next to each other, where Davina asks Dean if he wants to be in a relationship with her.

"I do," he says. WOAH.

Things then cut to shots of them embracing in a busy street, in what appears to be a secret meeting, then cuts to them on a couch in a hands-on embrace.

It's not just the viewers who will be shocked by this deception, as the relationship experts appear to look on at their behaviour in horror.
