He explained that completely changed his diet due to battling diabetes and added that while he was tempted to go under the knife he instead decided to get fit and healthy the old fashioned way .

While Katie put on a glamorous display in a burgundy turtleneck and black leather skirt, that highlighted her tiny waist.

Sharing the snap to his Instagram Stories, Mark wrote: ‘Co-parenting in London part two – Natural History Museum. Little Monster LOVED the T-Rex in a Christmas jumper.’

The exes previously treated Lawrence to a day out at the Harry Potter Warner Bros. Studio Tour in London on Saturday.

Mark, known on the ITV1 show as ‘The Beast’ – was left heartbroken when Katie, who is his second cousin, began seeing her lover Scott Bate for 18 months leading to the end of their romance.

They blamed the lockdown, mental health and their vast age difference as the causes for the end of their marriage. 

He went on to date Hayley Palmer, but revealed they had split in May, just days after their one year anniversary.

Last week, Mark revealed the heartbreaking reason he and Hayley split, after she claimed he dumped her because he ‘didn’t want to divorce his ex-wife’.

However, he has admitted it was because he ‘got old’, telling The Sun: ‘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.’

After Hayley said she couldn’t bear to think about Mark with another woman, the mastermind insisted that he isn’t actively dating.

He added: ‘There’s been no one since Hayley, I’m not saying there won’t be another one. But I’m certainly not looking.

‘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.’

This month, Hayley confessed thinking about Mark with anyone else ‘brings it all back’ as she spoke candidly six months after the pair’s break up.

Hayley admitted she was forced to turn the TV channel over after seeing him on Loose Women as she admitted she found it ‘triggering’. 

Speaking to MailOnline, Hayley confessed: ‘It was really upsetting seeing him pop up on my screen, and I had to turn over. I didn’t expect it to feel like that. 

‘As the last time he was on there, I was sat beside him and we were speaking about celebrating our one year anniversary and then exactly one week later my world came crashing down. To be honest thinking about him with anyone just brings it all back.’ 

Hayley explained she was taken aback by her feeling as she continued: ‘It was triggering. I didn’t think it would be as I have worked really hard on my mindset and have been in a good place.’
