Rita Ora has been forced to cancel her appearance as the headline act at the Secret Solstice Festival.
The singer was due to perform at the event in Reykjavík, Iceland, but has had to pull out due to ill health.
Announcing the bad news on her official Facebook page, Ora explained that a re-occurring chest infection was the reason for her absence from the music festival.
In a heartfelt post, she said: “I'm very sad to have to let all those attending the Solstice in Iceland know that I'm not going to be able to headline as planned.
“I've been struggling with a re-occurring chest infection and have been advised by my Doctors to take time out to recover.”
Revealing how heartbroken she is by the cancellation, Ora continued: “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.
“I'm especially disappointed and heartbroken when it means letting down my wonderful fans.”
She concluded the post by promising that she would be at the event next year.
“I'm so sorry to not be there! I love you all and thank you for your support. I look forward to celebrating Solstice 2020 with you!”
Fans were quick to send their get well wishes to the star.
“Get well soon Rita. It is important to take the doctors advice on things like this,” wrote one concerned fan.
Whilst another commented on the social media site: “Get well soon love, rest rest rest and plenty more rest.”
“Get well Rita. We all are human and understand that,” a third user posted underneath her announcement.
It is not known who will replace Ora as the headline act.
However, festival goers can still expect to see performances from acts including Jonas Blue, Black Eyed Peas and Robert Plant and the Sensational Spaceshifters.
