MAFS UK star Kieran speaks out after clip of him kissing another bride causing wife Kristina to break down in tears is revealed

Married At First Sight UK star Kieran has spoken out after clip of him kissing another bride was revealed.

Now, it's generally been a very dramatic this week on the Channel 4 programme and, specifically between power couple Kieran and Kristina, it's been quite the emotional rollercoaster.

An earlier episode saw the groom express his concern over his wife's battle with PMDD, after which viewers thankfully praised him for supporting her though it and vowing to give their marriage all he could.

However, after E4 shared a preview for tonight's episode (24 October) of Kieran appearing to get intimate another bride during a group dinner party - concerns were at an all-time high.

The clip shows Kieran leaning down to kiss his co-star Polly - who herself is paired up with husband Adam - on the lips.

Now, while the smooch appeared to have been in jest - with Kieran, Polly and Adam laughing it off - Kristina appeared far from amused when the camera panned over to her.

"Did you just kiss another wife?" she demands to know as he struts over to her afterwards.

Later, breaking down before her fellow brides, Kristina confessed: "I'm gutted." Take a look at the awkward scenes below:

MAFS UK fans have since rushed to social media to share their reactions to the scandal with one Instagram user writing: "Naughty naughty."

"Why?? Why would you do this..." hit out a second.

A third chimed in: "I’m not sure about these two now."

"Oh Kieran how could you..." scolded another and a final Instagram user echoed: "Ohhh don’t you go breaking that beautiful kind hearted soul @kristinagoodsell's heart!"

Kieran has since addressed the now-viral clip, taking to Instagram himself to share a series of four photos of him, Kristina and the other contestants at the dinner party.

He captioned the series of snaps with quite the teasing message.

"Did someone say 'let’s get f*cked up and have a dramatic dinner party?'" Kieran penned before he finally confessed: "I might have ACCIDENTALLY pecked another bride on the LIPS. #woops."

Cryptically, the reality TV star made sure to add: "@kristinagoodsell has the patience of a saint, and I’m super grateful for her."

Well, I guess we'll simply have to sit back to wait and see what happens between the pair in tonight's eagerly-anticipated episode.

Married at First Sight UK airs every Monday to Thursday at 9.00pm on E4.
