While New Zealand’s season of Married At First Sight recently came to an end, the UK version of the show is only just getting started and it’s already seen some drama. 

Yesterday, the first couple of the new season of the reality show, in which complete strangers meet at the altar and go on to become husband and wife in a bid to find true love, were revealed and it seems they have gotten off to a rocky start. 

Becoming the first couple to say “I do” in the new season was dog walker Kristina, 30, and Kieran, a 28-year-old mechanic, but before they could even exchange vows, the groom appeared to show his to-be wife what to expect from their marriage. 

In a teaser video shared on the MAFS UK Instagram account, Kieran can be seen with a pair of false teeth in his mouth as he watches Kristina walk down the aisle. 

He got their friends and family in on the gag as well as he turned to them and placed his finger to his lips, signalling them to keep his prank a secret. 

Upon reaching the altar, the nervous bride turns to her groom and asks, “Are you alright, are you okay? What’s your name?” 

It then cuts to her speaking to producers, admitting, “These teeth. What the f**k?”

While the two do go on to tie the knot, Kieran admitted the teeth were his way of not only managing his nerves but to also figure out what kind of woman he was marrying. 

He told producers, “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.” 

Kieran’s prank has already gone viral on social media, with many confused whether or not those are his real teeth. 

One person wrote on X, “this has me crying surely he has fake teeth in??” 

Another wrote, “Omg that sneak peek of mafs uk that guys teeth?? Why would you not get them fixed?? Dentist exits and orthodontics and veneers omg.” 

Others made their opinions very clear, with one person on Instagram stating, “The fact he would do that is an instant ick.”

Ick is Gen Z slang for a sudden dislike of someone or no longer being attracted to them because of something they do. 

Some fans of the show appeared to find the funny side of it though, “Toooo funny!” One person wrote. Another added, “Screaming! I cannot wait for this!”
