Lewis Capaldi has admitted he feels relieved to be "the poster boy for Tourette's" because he was convinced his tics were a sign of a degenerative disease.
The 'Someone You Loved' singer recently shared how he had been diagnosed with Tourette's syndrome after noticing symptoms including twitching in his shoulder while on stage.
Capaldi is a guest on this week's Jonathan Ross Show, where he says: "I do have Tourette's. I didn’t mean for it to be a big thing. I twitch a lot. My left shoulder goes up and I do this with my head. Now I am the poster boy for Tourette's. I’ll take it, I’ll gladly accept that.
"It was seven or eight months ago [that I was diagnosed]. I thought I had a degenerative disease. So to be told it was in fact that I have Tourette's, as you can imagine, was quite a relief. It’s fine. Everything works…"
He adds: “I thought I was quite alone in being twitchy. It’s been a relief and, if anything, nice to know I have a community. I’m quite an anxious person, I really start to overthink things if something’s wrong - this was a weight off my mind.”
The Scottish star says that he finds his condition easier to deal with if he keeps up with regular exercise and doesn't drink too much, but admits: "It definitely gets worse sometimes on stage. Sometimes it can really affect my performance."
Elsewhere in the episode, which also features Daisy May Cooper, Romesh Ranganathan, Tim Peake and Chloe Kelly, Capaldi shares the story of his nerve-racking shot-for-shot remake of Wham!’s Club Tropicana video.
He says: “Shooting it was awful. I had sickness and diarrhoea during it. I swear on all that is holy that my hole was unholy.
“It was a difficult two days. We weren’t allowed to drink during it. I had to wear those white pants all the time. We didn’t have spares. I had to ‘clench cheek’ the whole time.
"It’s a very strange feeling that at any point you might be betrayed by your a***hole.”
The Jonathan Ross Show airs on Saturday at 10pm on ITV.
