"It just happened." The Chase Australia's Mark 'The Beast' Labbett on marrying his cousin.

The Chase star Mark ‘The Beast’ Labbett has reunited with his wife, who also happens to be his cousin.

The couple split in May this year after Katie had an ongoing affair.

Following news of the affair, Mark spoke publicly about discovering he had married his cousin after their 2014 wedding.

It’s understood their fathers are first cousins, making the pair second cousins. The couple, 53-year-old Mark and 26-year-old Katie, also have a son, whose name and identity has not been publicly disclosed.

Appearing on UK morning show Loose Women at the time, Mark told the panel that after he married Katie, he discovered they were cousins.

“It wasn’t something we were aware of at the time — it was one of those things that happened,” he said.

He then spoke about how difficult it was to adjust to married life, adding, “I’d been a single man for a long while so I was getting used to the idea of being on my own.

“A bachelor can be pretty selfish, you get used to doing what you wanna do all the time.”

The Mirror, however, tells a slightly different story.

According to the publication, Katie posted to Facebook prior to their wedding with the status: “So… I’m getting married… TOMORROW!!! Feeling in love.”

In earlier posts, she is reported to have said about Mark, “He’s my cousin and the chaser on ‘the chase’.”

In April, reports emerged that Katie had been cheating on Mark for more than a year.

The Sun claimed Katie had been seeing her new boyfriend 28-year-old Scott Bate since 2017, and since deleted Facebook photos suggest the pair had taken numerous trips together and spent time with friends as a couple.

Katie confirmed their split in May, telling The Sun:  “Mark and I had been talking about separating for some time — we have been drifting for a while. He works away a lot and that’s been hard. A lot of people think it’s the age difference but we don’t see that as the factor”.

“It’s more that we don’t have mutual friends, and our lives are just very different. I met Scott by accident, on a night out, and we just clicked. It wasn’t intentional, it just happened…”

After a separation of four months, Mark and Kate are now reportedly back together.

On Tuesday, during another appearance on Loose Women, Mark said the couple are trying to make things work.

“Like a lot of relationships, you go through a rough patch. We’re working our way through it,” he said.

“But we’ve always tried to be quite private. We’ve never done the glossy magazines. A tabloid newspaper offered us a sum of money to give us an exclusive. And we respectfully declined. It’s not what we do. You won’t find a picture of our son anywhere on the internet because it’s been quite a deliberate decision,” he added.

“Nor am I going to name him again. If he wants to when he’s old enough – to have a social media profile, that’s up to him. But I’m not going to do it for him.”

When asked to confirm whether the couple were back together, Mark flashed his wedding ring in response.
