If you know heatworld, then you'll know we're experts of reality TV.
We know all the Love Island couples that are still together and we know all the iconic Big Brother stars that's ever graced our screens.
However one show that truly is the gift that keeps on giving is Married At First Sight. We're on series nine of the UK show and honestly, these contestants know how to keep us entertained.
So much so, they may even take things a little too far because some of them either walk out of the experiment or they're axed by producers.
Don't believe us? In all nine series of the UK show 15 contestants have either walked or been asked to leave the show, so we've had a look back at all those reality stars...
Sam McDonald and Jack Finn-Kelcey
Throwback to the first ever series of MAFS UK and one couple didn't even make it down the aisle together. Sam McDonald and Jack Finn-Kelcey were meant to tie the knot but during the very first episode, viewers were told, 'The prospect of marrying a stranger is too hard for some of Sam's family to accept and so for Sam and Jack, the experiment comes to an end.'
In a bizarre twist though, they met up outside the show and started dating but it didn't last and they've since split.
Wayne and Carrie
The first few seasons didn't have much luck because during series three another bride and groom failed to make it down the aisle. Before even meeting on their wedding day, Wayne pulled out of the experiment and explained, 'I really do hope Carrie understands my decision and obviously she'll be initially gutted, if she was enjoying the whole experience then it's coming to an end for her as well but I couldn't go through with it just for that.'
Nikita Jasmine and Ant Poole
Series 6 of MAFS was when things got dramatic and Nikita Jasmine became the first contestant to be removed from the experiment. Nikita and Ant Poole were doomed from the beginning tbh. She made it clear that he wasn't her type on paper during their wedding, they argued during their honeymoon and then she was removed after a dinner party.
An E4 spokesperson said, 'During filming, a situation escalated off camera and Nikita displayed a level of aggression that was unacceptable and breached our agreed code of conduct on behaviour. As a result, she was asked to leave the experiment.'
Brad Skelly and Shona Manderson
It was during series eight that we waved goodbye to a lot of the contestants. First up was Brad Skelly and Shona Manderson who seemed to hit it off but after love bombing accusations and passive aggressive rows at the dinner parties - Paul C Brunson and Mel Schilling stepped it and removed them from the experiment.
Luke Worley and Jay Howard
Another series eight couple who were forced to leave the experiment early was Luke Worley and Jay Howard. It wasn't even their relationship that got them kicked off the show, it was actually Luke's physical fight with Jordan Gayle. The camera crew filmed the whole fight and during a commitment ceremony the expert told Luke that he had to leave the show.
Terence Edwards and Porscha Pernelle
Terence Edwards and Porscha Pernelle failed to hit it off from the get go and he event voted to leave during week one. They managed to say a few weeks but after Terence voted to leave and Porscha voted to stay (which usually would mean they both had to stay in the experiment), he made it clear that he was leaving the show regardless.
Nathanial Valentino
Nathanial Valentino decided to quit the show after it came to light that. Things weren't really going well for Nathanial and Ella Morgan from the get-go. Nathanial and Ella had a screaming match during their honeymoon but Ella having a fling with JJ Slater was the final straw and he quit the show. He didn't even return for the commitment ceremony on reunion episode.
Mark Kiley and Sean Malkin
Mark Kiley and Sean Malkin's relationship came to an end during a dinner party. Sean asked Mark for a private conversation and told him, 'I need to be true to myself on this one, and after this letter as well, I don't see this going any further. I'm going to leave.'
