Sam Smith has cancelled upcoming concerts in Birmingham and Glasgow on doctors' advice, after having to stop Manchester gig just four songs in due to "a vocal cord injury".
A spokesperson said on Instagram that medics recommended a "complete vocal rest".
The singer said refunds are available.
The singer, who uses them/they pronouns, had to cut short Wednesday's gig at the AO Arena in Manchester, after having started promisingly with a performance of the hit Unholy, just hours after teasing a show "surprise" on social media.
But fans were soon left bewildered when the venue went dark, the concert ground to a halt and the star left the stage.
The crowd was then informed Smith was facing "vocal issues".
