DELTA Goodrem has postponed her upcoming UK tour after losing her voice. 

The Australian singer-songwriter had been due to perform at Glasgow's O2 Academy on Wednesday, April 5 as part of her Hearts On The Run tour.

However, in a post shared on Instagram, the Born to Try singer revealed she made the "difficult decision" to reschedule after doctors ordered her to go on "strict vocal rest" after overusing her vocal cords.

She wrote: "It hurts my heart to have to share with you that we've had to make the difficult decision to reschedule my upcoming UK and European shows. 

"I am feeling so grateful to be this busy in this moment of my career, but from overextending myself on a number of projects, including preparing new music for you all, I unfortunately have overused my vocal cords to the point of me having no voice for extended periods of time. 

"I have been pushing through this month believing my voice would heal but as I sit here typing from rehearsals with a ready show, my doctors have just ordered me to go on strict vocal rest and not sing.

"I am so excited to have an incredible year of touring ahead. 

"Nothing makes me happier than being on stage and performing for you in full flight."

Delta said the shows will be rescheduled "as soon as possible" and tickets will remain valid for the new dates. 

One disappointed fan wrote on Twitter: "The news of Delta Goodrem having to postpone her UK/EU tour is NOT what I wanted to hear this morning.

"Whilst I understand it’s for a good reason if she’s lost her voice, I’m now scared in case the new Glasgow date clashes with another gig I have lined up. I hope not!"
