Jess Glynne took advice from Sam Smith about her vocal cord surgery.

The 'Hold My Hand' hitmaker turned to the 23-year-old singer when she began having issues with her voice, with the 'Stay With Me' crooner putting her in touch with a surgeon who recently performed similar surgery on him.

She said on Instagram: ''I realised I had a problem with my voice and asked Sam for advice. He put me in touch with Dr Zeitels who I met with last week.''

The 25-year-old chart-topper - who is set to release her debut LP 'I Cry When I Laugh' in August - cancelled her set at Isle of Wight Festival on Saturday (13.06.15) due to her vocal issues, and has now had to pull out of her scheduled Glastonbury Festival performance and a tour supporting John Legend as she won't be able to speak for three weeks.

Writing on her account, she added: ''I won't be able to talk for three weeks but I will be back singing in August and in plenty of time for both my big UK tour and my first ever American tour, both of which I'm massively excited about. I'd like to take this opportunity to say thanks to my fans who've been very supportive and gave me my first solo number 1 with Hold My Hand (sic).''
