Married At First Sight UK bride has explicit three-word response after seeing husband for first time at altar

A Married At First Sight UK contestant's heated reaction to her future husband pulling a horrific prank on her at the altar of their wedding has gone viral online.

Channel 4 released a controversial teaser yesterday (21 Aug) ahead of the incoming 2024 instalment - which will land in September - and let's just say, it's a pretty difficult watch.

In the video, a 28-year-old mechanic named Kieran can be seen waiting patiently at the front of a church for his 'match-made' wife to appear around the corner.

It quickly becomes apparent, however, that the Geordie thinks himself quite the comic, after he bared his teeth to show spectators a hideous set of false nashers.

His lip visibly protruding in an attempt to disguise his prank, Kristina's bridal party were quick to notice something was wrong as they filed into the church's pughs.

Several bridesmaids even took one look at their gal pal's future parter, and were left visibly perplexed.

Kieran then 'icks' viewers out even further by raising a finger to his lips, as if imploring with the guests to remain silent on his prank.

And when Kristina finally arrives before him, Kieran breaks into a wide grin, showing off a set of broken and rotting false teeth.

At first, the blushing bride bursts into a fit of laughter, seemingly understanding that the groom's presentation was simply part of a practical joke.

When Kieran appears confused, however, and refuses to take them out, she quickly becomes alarmed, her face going red with embarrassment.

He then asks her through a mess of plastic teeth: "Are you alright, are you ok? What's your name?"

Before Kristina has a chance to reply, however, a hilarious voice-over thunders through, before the horrified bride issues a pretty explicit statement.

"These teeth. What the f**k?" she exclaims.

Giving a glimpse into the reasoning for his prank, Kieran tells viewers: "I think the teeth could make us look a little bit immature. I'm a little bit nervous to see how it goes.

"This could really end up bad. I just want to know if this girl's fun."

By the sound of viewer reaction, however, audiences also seem under the impression that Kieran's prank went down like a lead balloon.

"The fact he would do that is an instant ick," one MAFS UK fan penned in the comments after E4 shared the cringe-worthy clip on social media.

Another added: "Being able to take a joke is very different from putting up with immaturity. I think that's hilarious but definitely isn't appropriate under those circumstances."

"No thanks! Reminds me of something my ex would do and that’s why he’s my ex! Constantly p*ssing around and loving being the centre of attention," a third continued.

This should be an interesting series, eh?
