MARRIED At First Sight's Arthur and Laura are on the rocks in tonight's episode - after he dropped a huge revelation.
The couples reunited for one final dinner party but things took a sour turn when Arthur revealed a shock detail about his past dating history.
Sitting at the table, Georges, who is married to Peggy, asked the tennis coach when his last date was before the experiment.
Arthur nonchalantly replied: "A week before it," which prompted a horrified reaction from the rest of the contestants - including his wife Laura who looked mortified.
Ella piped up and said: "Arthur, you've done it again darling. It's 10 weeks and you still can't learn."
Arthur laughed as he tried to make light of the situation and said: "I had a date literally maybe two weeks before I walked in here.
"It wasn't great, it was nothing."
He then told the camera: "I went a date, nothing happened. I got married two weeks later...big deal."
Clearly unimpressed by his comment, Laura fought back and said: "That just makes me think that you weren't taking it seriously."
Arthur replied: "Nothing happened, it was nothing," as Laura explained: "Me and you were about to get married."

He then interjected: "It doesn't matter," but this didn't sit well with Laura and she exclaimed: "Don't tell me it doesn't matter, I will decided if it matters to me or not."
She later told the cameras: "Dating someone a week prior to getting married to me, obviously he didn't take this seriously.
"I'm furious, I actually can't even look at him."
It looks like this was the beginning of the end as it was revealed last month that their marriage appeared to be over after he was spotted snogging a mystery woman on his birthday.
The reports that Arthur and the woman "spent the entire night together" as he marked his 35th birthday with some of his MAFS UK co-stars.
The likes of JJ Slater, Jay Howard, Luke Worley and Peggy Rose were in attendance.
However Laura was noticeably absent from the night out.
While her castmates were pictures and videos from their night, Laura took to her Instagram story to see if she could find someone to do her hair.

Sharing a stunning snap selfie, Laura asked: "Do I have any hairdressers that follow me local to Hampshire/West Sussex or London that can fit me in for a colour this week please."
She and Arthur seemed to hit it off from the very start - but things soon began to crumble when he revealed he had found his vows off the internet, while homestays were also a disaster after he clashed with Laura's best pals.
