KT Tunstall has pulled out of her summer tour dates over fears she could suffer hearing loss.
The Scottish singer was due to support pop duo Hall & Oates and headline her own tour but has now cancelled due to issues with her right ear.
It comes after the Suddenly I See hitmaker lost hearing in her left ear in 2018.

Tunstall, 46, shared the news about the "extremely difficult" decision in a statement posted to Twitter.
She wrote: "Permanently losing 100% of my hearing in my left ear whilst on tour in 2018 was an enormous shock, and the result of touring without adequate periods of rest, which caused an acute physical breakdown.
"After a recent run of consecutive shows in July, I have experienced some issues with my right ear; a small amount of tinnitus – which is exactly how the breakdown of my left ear began.
Sending love & thanks in advance to those of you who will have to wait a little longer until I see you, but I promise I *will* see you soon - in rude (and rocking) health! 🙏🏼⚡️
Much love, KT x pic.twitter.com/tu1T7TC0i9

"My thoughts on touring so intensively and consecutively have made me question whether my remaining hearing will be able to handle it."
Tunstall added that in order to "move forward safely" she would need to have adequate rest between shows.
"With regret and sadness, this means I will no longer be able to join Hall & Oates on their incredible tour.
"It is hard to fathom pulling out of such a wonderful opportunity," she went on.
Tunstall said all tickets for her headline shows would be honoured for new dates in 2022.
Tunstall shared earlier this year that her hearing loss was a result of exposing her ears to loud music without adequate protection.
While she has suffered with tinnitus for around a decade, in 2018 she also developed sudden sensory hearing loss, which led to total deafness in her left ear.
