June 7 (UPI) — Singer-songwriter Charlie Puth canceled Saturday’s show in Orlando, Fla.

“I am so devastated to do this, but I have to cancel tonight’s show,” Puth, 34, wrote on his Instagram Story.

“I’ve been sick for the last few days and am now being instructed to rest or else risk canceling more dates on this tour. Performing for you all each night means everything to me, and you all deserve the best. I’m heartbroken, but I physically am unable to perform. Without a voice, I can’t give you guys the show you all deserve. I’m so sorry, this was not an easy decision to make but I hope to see you all soon when I am well again.”

Puth kicked off his Whatever’s Clever world concert tour in April.

He is next slated to perform Tuesday in Nashville.
