Married At First Sight UK is bringing the drama this series, as the first weddings have taken place - but one couple hit the rocks big time.
Just days after one ceremony, a honeymoon led to heartache on Wednesday night as claims of cheating were shared.
Groom George was quick to quiz new bride April over the encounter, with a teaser on Tuesday night revealing she had kissed someone else while on their honeymoon.
As the episode played out, George asked April about the kiss she shared with a woman behind his back - a fellow hotel guest.
George was gutted and revealed: "I've been cheated on."
It all kicked off when during the honeymoon, April felt George was being a bit intense, and she wanted some space.
George took offence and confronted April about what she wanted, with her telling him she was overwhelmed and "needed a breather".
He ended up slamming his cocktail down and storming off, saying: "Here's your space then."
Just when things couldn't get any worse between them, despite George apologising for his behaviour, the kiss news emerged.
Soon things escalated, with George breaking down in tears on camera.
He detailed: "I woke up this morning numb and cold. Yesterday we ended up having a lovely evening. Then I went away for a short while, I came back and realised there had been an incident.
"I don't know if I feel comfortable doing this. It was heartbreaking and a massive kick in the teeth. She's been intimate with somebody else. I've been cheated on. F**k, sorry..."
George then began crying and walked away, unable to continue on camera.
As April went to see him, she brought him a bottle of drink as a peace offering before asking why he stormed off.
April then claimed it was a game of "dares" and she kissed a girl in a hot tub as part of a dare, with her seeming baffled as to why he was so upset.
She told him: "We were all mucking around, playing dares and stuff, having a laugh."
This led to George asking if she had kissed more than one person, to which she replied: "No of course not, I'm really sorry ig it has upset you but I didn't even think anything of it. It really was nothing, it wasn't."
Viewers were stunned by the moment just days into the show, and the pair's marriage, after they seemed to get on well during their ceremony.
Many fans were divided over who was in the wrong, with one writing: "Goodness me, April kissed someone else on her HONEYMOON, she doesn't think it's a big deal and George is the one who apologies??"
Another agreed: "April needs to grow up, about 'dares'. You're 32 luv," as a third said: "April thinks her actions are innocent because it was a dare! Wow!"
Others backed April though, with one writing: "Sooooo April kissed another girl for a dare???? Was that all???"
A second commented: "I was just about to give April the worst contestant crown and then it turns out shes kissed a girl in the hot tub. Rude yes, reason to scream cheating and drama meh not so much."
It had been teased an explosive moment was on the way, as dating expert Paul Carrick Brunson spilled on Twitter.
He hinted it would possibly go down as the most talked about moment in the show's history, leaving fans wondering what had happened.
Paul said to viewers on Tuesday: "The trailer has everyone worried. I get it. I predict the moment they are referring to will be one of the most talked about in MAFSUK history."
Married At First Sight UK airs weeknights at 9pm on E4.
