Rita Ora has been forced to cancel her appearance as the headline act at the Secret Solstice Festival in Iceland's Reykjavík due to ill health.
The singer posted a string of messages on Twitter saying doctors had advised her to cancel due to a "re-occurring chest infection".
She says she's "heartbroken" to disappoint her fans.
"I was so excited to spend time in Iceland and be part of this festival. I never take any cancellation lightly as I'm always hugely grateful for all the opportunities I have to perform as I love performing," she wrote.
