She has had to cancel her gig near Pickering on Saturday - and a number of other shows in the Forest Live series - and the concerts cannot be rescheduled. Ticket holders will be contacted by their point of purchase to arrange a refund.
Jess Glynne issued the following statement: ‘It absolutely kills me to say this – especially given what has happened in the past few weeks – but on the advice of my throat surgeon, I am going to have to cancel my next shows through until July 14th and I hope to be back as soon as possible after that.
"I know many of my fans feel I let them down so badly when I pulled out of the Isle of Wight festival but the reason I knew I just wasn’t going to be able to make that performance has now been made clear to be by my doctor, Dr Zeitels.
"It is true that I went out and celebrated the end of the Spice tour. That was a massive high for me and I wanted to mark it with the women who’d become friends and mentors to me.
"But I had also been suffering on and off for weeks with anxiety about my voice. It wasn’t right. I wasn’t sounding my best and I felt there was something wrong.
"Two days ago I came to Boston to see my surgeon who told me my vocal chord has haemorrhaged and that if I wanted to remain as a performer I needed to urgently take a break, rest my voice completely for the next 10 days and try and remain in total silence to give my vocal chords a chance to recover.
"Basically he told me I have been completely overdoing everything. In the last six months I’ve performed almost 100 shows, I’ve pushed through at times when I know I’ve been tired and overstretched and I got to breaking point, my voice literally got to breaking point.
"The thing is I am my voice. If my voice goes, I go. I am so privileged to do what I do, I am so privileged to have fans out there who come and see me.
"But I never want to be less than 100 percent. I never want to give you less than 100 percent. I am so devastated to be letting anyone down but I want you to know the full truth of my situation so you understand why I have to do this.
"All I know is I have to go away, look after my voice and come back stronger, better and be the performer my fans truly deserve."
