The Chase star Mark Labbett shows off 10 stone weight loss as he poses with unrecognisable ex-wife

MARK Labbett was beaming as he spent a second day with his ex-wife, Katie.

The couple, who married in 2014 but split in 2020, have been treating their son, Lawrence, for a weekend in London.

Navigating co-parenting like pros, Mark shared pictures from their two big days out, which started on Saturday with a trip to the Harry Potter Studio Tour in Watford.

Today, they shared another photo, showing off their shared transformations as Mark wrote on the pic: "Co-parenting in London part two - Natural History Museum.

"Little Monster LOVED the T-Rex in a Christmas jumper."

Both Mark, 58, and Katie, 31, looked unrecognisable from their time being married, having both lost weight and switching up their looks.

Mark looked slender in a grey jumper and black trousers next to Katie, who cuddled up beside him in a black skirt and maroon jumper.

The new pic comes a day after the family spent a day at Warner Bros Studios to take in the Harry Potter tour with their son.

While keeping "Little Monster" Lawrence away from his social media, Mark and Katie snapped a selfie together which he shared on his Instagram Stories.

Mark and Katie, who are also second cousins, were together for seven years, but split when their attempts at an open marriage failed.

They first started speaking on Facebook in 2010, unaware of their familial connection.

Mark, best known as The Beast on the ITV quiz show, later admitted that Covid lockdown had a detrimental effect on his mental health, and amplified the pair's 27-year age gap.

Despite the break-up, they are yet to officially get divorced, though both have gone on to other relationships.

Mark split from Hayley Palmer this year just a week after their one-year anniversary, with Hayley later claiming Mark had no intention of officially divorcing Katie.

Speaking exclusively to The Sun about his break-up this week, Mark said: "She's [Hayley's] a lovely lady and I was very lucky to date her for a year, and as I said...it's me, I got old."

"There's been no one since Hayley, I'm not saying there won't be another one. But I'm certainly not looking."

Opening up about being content as a single man, Mark said: "I joke I am a shed man - a guy of a certain age that's quite content being in or out of a relationship - but loves to be spending time on their own.

"It's primal, I think it goes all the way back to the hunter-gatherers where the man would go off a lot of time on their own.

"To be fair it's not just men, there are people who actually like their own company."
