Jess Glynne is to undergo vocal cord surgery.

The 25-year-old singer will have emergency surgery on her voice next week, having cancelled her planned performance at Isle of Wight Festival over the weekend after doctors said she was too ill to perform.

Revealing the news on Instagram, she said: ''I am so so sad to tell you that I'm having to have vocal surgery next week. (sic)''

The 'Hold My Hand' hitmaker - who is most well known for providing the vocals on Clean Bandit's Grammy Award-winning hit 'Rather Be' - revealed the sad news means she has had to pull out of forthcoming performances.

She said: ''I'm so sorry and it kills me but I have to cancel some forthcoming shows and festivals. I'm a little scared but I will be back singing better than ever very soon! Love hugs and kisses Jess xxx (sic).''

The fiery haired musician previously said she was ''devastated'' at having to ditch her slot at Isle of Wight Festival - which Ella Eyre instead performed in - indicating she hoped she would be well enough for her scheduled performance at other events such as Glastonbury.

She wrote on Twitter: ''I'm so devastated and sad to announce that I won't be performing at the Isle Of Wight Festival today. I haven't been well and my doctor has told I'm not allowed to sing. I'm so sorry if I have let anyone down! I'm gutted!I will get better as soon as possible and I'll be back to make it up to you! Big love and hugs and I hope you understand and hope everyone who is going has an amazing day! Wish I could be there (sic).''
