Comedian Miranda Hart has said taking part in BBC reality show Celebrity Traitors will be challenging on her body as she continues living with ME. The 53-year-old actress is making her television comeback on one of the most physically and mentally demanding reality programs after years away from the spotlight.

Speaking before entering the Scottish castle where the series is filmed, Hart explained that while she still experiences fatigue and pain caused by her chronic illness, she now feels well enough to step back into work and believed the show was the perfect opportunity.

Hart shared in her 2024 autobiography how her Lyme disease, which developed into myalgic encephalomyelitis (ME), left her bedbound and without joy. But when offered the spot on the BBC series, she recalled: "I haven't done much TV work for a long time, having only recently come out of long-term ill health issues, and when I was offered this, my whole body sort of relaxed, I smiled, and I just wanted to jump about like a schoolgirl with joy."

Hart explained that she is still living with elements of ME, bringing fatigue and pain that she must manage. "I'm still living with elements of ME, and that brings fatigue and pain to manage, but I have come to a point where I feel well enough to step out, and that's also partly why I'm doing this," she said.

"The joy of mucking about on television again will hopefully outweigh some of the challenges," she continued. "And I think it will be challenging on my body, so it'll be interesting, and it'll take some courage as this is a big next step."

Hart noted that living with a chronic illness is invisible. "When you live with a chronic illness, it's invisible, so people don't know that you're sitting there in pain. But then it reminds you that everybody's got their thing," she explained. "So, I'm also really looking forward to making friends and looking after each other and hopefully they can carry me up a hill or whatever we're going to have to do!"

Medical diagnosis and career background
It took medical professionals 33 years to discover that Hart had been battling Lyme disease, a bacterial infection spread to humans by infected ticks. Medics had initially mislabelled her symptoms as agoraphobia, an anxiety disorder characterised by symptoms of anxiety in unfamiliar situations. Her condition later developed into ME, also known as chronic fatigue syndrome, a long-term illness that causes debilitating fatigue not improved by rest.

Following her mainstream success with her hit 2009 BBC sitcom Miranda, which cemented her status as a comedy legend, Hart remained largely out of the spotlight in recent years. Her television appearances were limited to guest spots on chat shows and appearances for Comic Relief.

Galloping dares and Highlands arrival
Hart revealed that fans have challenged her to perform her iconic trademark gallop through the castle corridors during filming. "When someone said on Instagram, 'Oh, I hope you gallop in the castle,' I foolishly replied, 'Right, I now take that as a dare.' So that was idiotic of me," she admitted.

"I will have to at some point gallop down a corridor," she added. "I'll gallop when no one's watching... or who would be the best person to encourage to gallop? I don't know. I mean, Kenny probably doesn't even know who I am. So, if I could get him to gallop... I could get a new generation galloping."

Hart was joined in Scotland by her rarely seen husband, Richard Fairs, 60. The couple, who tied the knot in October 2024, landed at Inverness Airport in a private jet ahead of filming.

Hosted by Claudia Winkleman, Celebrity Traitors will see contestants play a game of detection, trust, and betrayal in the Scottish Highlands in the hope of winning a cash prize up to £100,000 for a charity of their choice. The series starts on Thursday, October 1 at 8pm on BBC One and BBC iPlayer.
