While many may have chosen to leave the show as a couple, what many want to know is if they're still together?
Of course, we won't find out very much until the Married at First Sight UK reunion airs on Monday 4th October.
The success rate hasn't always been great on Married at First Sight UK, with most of the couples splitting after the experiment on previous series.
However, last year proved to be different, with 75 per cent of couples still together, including unseen couple Ally and Paul, who weren't able to film due to the pandemic, but met up outside the show and went on to have a baby.
Here's everything we know so far about the Married at First Sight UK 2021 couples, including those who have already split, and what happened to the previous years' couples, from series one stars Emma and James, to last year's contestants Michelle and Owen.
Nikita and Ant - Split
Nikita and Ant were one of the first couples to tie the knot on series six, but things didn't end well. Despite a lack of attraction on Nikita's side, the pair appeared to put things behind them and got on with their honeymoon. However, Nikita got very angry at the first dinner party, as she argued with Jordon. It was then revealed that Married at First Sight UK star Nikita had been removed from show for "unacceptable aggression" off camera, putting an end to hers and Ant's time on the show.
Ant re-entered the process with Alexis, but that didn't work out either.
Megan and Bob - Split
Despite Megan admitting she wasn't attracted to Bob, Megan and Bob stuck at the experiment for some time, before ending their marriage ahead of the home stays. Their relationship had been rocked by Megan's affair with Jordon – who she shared a kiss with after the first dinner – and the pair eventually decided to call it quits.
Morag and Luke - Still together
Sparks didn't fly when Morag and Luke met on their wedding day, and on their honeymoon, Morag didn't hold back, as she told Luke he wasn't her usual type and she didn't like his clothes. He decided to upgrade his wardrobe and after Morag bought him a fireman costume and they opened a bottle of bubbly. Things seemed good between them – that is until, Luke dropped the L-bomb and Morag didn't feel the same. And during the girls' day out, Morag admitted she didn't know how she'd react if her usual type slid into her DMs. The message got back to Luke, and he wasn't happy about it. Nevertheless, they agreed to continue in the experiment, only for one of Morag's friends to completely dismiss Luke during the homestays.
Despite differences, and a very interesting speech from Morag as she told Luke she came on the show to find a "ready made man" not a project, the couple decided to stay together at the end of the experiment.
Dan and Matt - Still together
Dan and Matt hit it off from the get-go, and only seemed to go from strength to strength throughout the experiment. The only issue they seemed to have was that Dan, 26, lived in Ireland, and Matt 39, lived in Leeds.
The pair decided to stay together at the end of the experiment, but viewers will have to wait until the Married at First Sight UK reunion to find out how things went for the couple outside of the show, and if they were able to make the distance work for them.
Marilyse and Franky - Still together
Things seemed to be going well for Marilyse and Franky until the matchmakers and other couples began to comment on their relationship, with many feeling that Franky could be "controlling" and Marilyse didn't open up.
Nevertheless, Marilyse, 37, and Franky, 47, continued in the experiment, with Franky – who resides in Dubai – considering moving back to the UK to be with his wife and her two sons.
The duo chose to stay together at the final vows, and judging by loved up posts on their Instagrams, it looks like they're still an item.
Amy and Josh - Still together
Despite their age gap, with Amy being 34 and Josh being just 26-years-old at the time of the experiment, Amy and Josh seemed to get on really well in the beginning. There was definitely an attraction between them, however, by the time they got to their honeymoon, cracks were beginning to show, as Josh labelled her "needy" and she got upset as she felt he wasn't being open.
The couple managed to work on things, and Josh even admitted he could see himself falling in love with Amy, however, the other couples didn't think they were strong enough – something that made Amy consider leaving Married at First Sight UK 2021 on many occasions.
Nevertheless, the pair managed to make it to the end of the show, and left as a married couple.
Tayah and Adam - Still together
There was an instant connection between Tayah and Adam, and on their honeymoon, the pair told each other they're in love. Things only got better when they returned to the UK and moved into their apartment together.
It's not yet know whether the pair stayed together at the end of the experiment, with Tayah, 25, and Adam, 26, still to make their decision at the final vows, but Adam previously revealed she'd be moving into his home in Doncaster, and the pair announced they were "expecting"... a little puppy.
In a preview for the final episode it looked like Adam might be having second thoughts about his marriage with Tayah, as he told a tearful Tayah there's "something missing", however, it was good news as Adam got down on one knee and proposed to Tayah.
The marriages on Married at First Sight UK are not legally binding, and are instead "commitment ceremonies," so the thing that was missing for Adam was to make it well and truly official.
Jordon and Alexis - Split
Jordon and Alexis just couldn't see eye to eye. After he admitted she wasn't his usual type and he preferred blondes, things just went downhill. And at the first commitment ceremony, Jordon revealed he'd shared a kiss with Megan, putting an end to his and Alexis' marriage.
Alexis and Ant - Split
After flirting at the first dinner party, Alexis and Ant asked Mel Schilling if they could reenter the experiment as a couple, but things never seemed to get off the ground for them. Alexis told the girls Ant wasn't being very forthcoming, and he admitted to the boys he wasn't attracted to her in that way and just saw them as friends. The pair ended up arguing at a dinner party, and later decided to leave the experiment.
Shareen and David – Split
Shareen and David were matched on the 2020 series of MaFS.
At 56-year-old, David – a sales director from Solihull, David – and Shareen, 47, made history as the oldest couple to ever be matched on the show.
The pair seemed to have a lot in common in the beginning, but things quickly changed on their honeymoon.
Shareen wasn't happy with his tattoos and survival kit containing massage oil, burning scents and 30 condoms.
Fans struggled to survive the shambles between David and Shareen, with many taking to social media to voice their concerns.
It will probably come as no surprise to fans then that the pair are no longer together.
Nevertheless, David did come to Shareen's defence on Twitter after the show, as some fans accused of her using the show for fame.
Responding to a fan who was sticking up for Shareen, he wrote: "Totally agree, sad we didn’t better connect, but that's life and the risk we accepted coming into this."
Shareen also opened up about her marriage to David, saying it was over in 48 hours.
In a face-to-face with the psychologist, Shareen said: "From day two, I knew there was a fundamental difference between us.
"The whole prepping and bag thing in case something bad happens – I feel nothing for that kind of world or that kind of mindset."
Michelle and Owen – Still married
Primary school teacher Michelle, 25, and IT manager Owen Jenkins, 31, seemingly hit it off from the get go.
She instantly felt "calmer" when she saw him and he was definitely attracted to her. However, the pair soon realised they disagreed on a lot of things when they moved in together at Owen’s parents’ house in Sheffield.
One year since the show, and Michelle and Owen are still together.
They have a joint Instagram account where they share loved up photos. Michelle officially changed her surname to Jenkins on her passport, and the pair met up with unseen couple, Ally and Paul, and their new baby over the summer.
Very cute stuff!
Steph and Jonathan – Split
They were the first couple to be matched on series four of the dating show, but unfortunately their marriage wasn't a match made in heaven.
From their honeymoon, it looked like things were off between them and the couple decided to call it quits at the final decision.
Speaking about their split, Steph said: "No regrets, weirdly. It’s a shame it didn’t work. I don’t think finding a husband is a thing that needs to happen.”
Verity and Jack – Split
Things looked promising for Verity and Jack. However, Jack later confirmed onscreen that their paring was over, because of “a missing jigsaw puzzle".
He said: “The last time I saw Verity was two weeks ago where I decided that we left it there and go our separate ways.
“It was hard making that decision and seeing someone get hurt. She is such an amazing girl, but I didn’t have that connection, that missing jigsaw puzzle, unfortunately we didn’t have that.”
Speaking about their break up, a tearful Verity said: “I really tried and I thought we were in it together, and were both gonna work at it."
Harriet and Richard – Split
When it came to science, Harriet and Richard seemed like the perfect match on paper.
But sadly, it just wasn't meant to be.
In the series finale, they filed for divorce after sleeping in separate bedrooms just a week into living together.
Speaking to the experts after making the decision to split, Harriet said: “Obviously I didn’t want, expect it to end in divorce so I think I definitely leave with a heavy heart.”
The feelings weren't mutual though, as police officer Richard, 28, admitted he would have liked to give it longer.
“It feels so rubbish to kind of not make your wife feel that way. I think deflated just hits the nail on the head," he said.
Stephanie and Ben – Split
Their chemistry was instant, with both feeling as though they'd met their perfect match.
But the cracks started to show when they moved in together.
Ben got cold feet and ran off to Portugal. They managed to patch things up when millionaire Ben whisked Steph away to one of his apartments in Cyprus.
However, one week after the show, Ben revealed he'd left her. He later went into the Celebrity Big Brother home and revealed that he was having a baby with his mystery girlfriend.
Lucie and Steve – Divorced
The couple split after six weeks together, but have remained friends. They regularly meet up for a chat over coffee.
Melissa and Clark – Divorced
Things looked strong for Melissa and Clark. The duo went through with their wedding and even moved in together at Melissa's London home. However, they didn't last and split after just five months.
Sara and Adam – Split
It looked like it was completely over for Sara and Adam, after the pair had a huge fight on camera as Adam got drunk on their honeymoon. Nevertheless, they moved in together.
Twelve months later, however, the broke up due to lack of chemistry.
Caroline and Adam – Split
Caroline and Adam made some steps in their relationship, moving in together and even getting a pet rabbit.
