Demi Lovato postpones concert after losing her voice

Demi Lovato postponed her latest gig after waking up with "no voice".

"This is the absolute last thing I want to do... I'm having so much fun with you all and I can't wait to see you again. Again, I'm so sorry and I appreciate your understanding. I love you all."

Demi, 30, kicked off her Holy Fvck Tour - in support of the album of the same name - on 13 August and it is scheduled to conclude on 6 November.

At the end of the South America leg of the tour in mid-September, the singer declared on her Instagram Stories that this trek will be her last.

"I'm so f**king sick I can't get out of bed," she wrote beside snaps seemingly taken in a hotel room. "I can't do this anymore. This next tour will be my last. I love and thank you guys."

If she is fit to perform, Demi's next gig will take place in Detroit, Michigan on Friday.
