Lewis Capaldi has been forced to reassure fans he's okay after a video of him twitching went viral.
The Scottish music star, 26, took to Twitter to remind fans that he lives with Tourettes syndrome - a condition of the nervous system which causes people to have certain 'tics'.
In Lewis' case, the Bruises hit-maker's tics may result in him suddenly twitching or jolt his shoulders with him having no control over his bodily movements.
Although Lewis has spoken openly about his diagnosis, a recent clip of his concert went viral on TikTok, and thousands of fans rushed to share their concern for the much-loved star.
Back in September 2022, Lewis first went public with the news that that he had been diagnosed with Tourettes Syndrome after he found out in March that he had been unknowingly living with the condition for years.
Addressing the video over the weekend, Lewis explained: "Hello it's Lewis here. I've seen this video here doing the rounds on TikTok and I see a lot of people in the comments concerned because I'm twitching quite a lot.
"I'm doing this quite a lot and look a bit uncomfortable. I've got Tourette's so I'm just twitching quite a bit but it's not an issue in the slightest. I'm absolutely fine.
"It's just that this happens when I get tired, nervous, excited or whatever so it just gets more intense. I'm not doing it now at all because I'm lying in my bed in my pants but this is at the end of an hour and a half gig and I'm singing in front of 15,000 people.
"So I'm tired and I'm very excited because this whole arena is singing my songs back to me but I'm fine. Thanks to everyone who came to the gig that night. It was incredible."
According to the NHS, Tourette's syndrome usually starts during childhood, but the tics and other symptoms usually improve after several years and sometimes go away completely.
There's no cure for Tourette's syndrome, but treatment can help manage symptoms.
Lewis previously admitted his decision to make his diagnosis public knowledge was due to the fact he didn't want his fans thinking he was 'taking cocaine or something', as he opened up about discovering he had the condition.
The Scottish singer explained how he was relieved to find out he had the condition because he originally feared he may have been suffering a degenerative disease.
"I have been diagnosed with Tourette’s," Lewis said in an interview with The Sun last year . "I wanted to speak about it because I didn’t want people to think I was taking cocaine or something.
"My shoulder twitches when I am excited, happy, nervous or stressed. It is something I am living with. It is not as bad as it looks."
Over recent years, a number of high-profile figures and celebrities have revealed they have Tourette's syndrome, including singer Billie Eilish who was diagnosed with the condition at the age of 11.
