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.
