“Unexpected but I'm here trying my best to not let it win,” the singer continued. “Sometimes admitting how you really feel can be the quickest road to recovery. And PLEASE know all of your understanding, love and support helps me so much. (And the morphine ) (And my Mums hugs) How are you today? Love Jess x.”

The 27 year old, whose real name is Jessica Cornish, announced she was in hospital earlier this week, posting picture of herself after her operation. While she didn't reveal what the surgery was for, she told her fans she wanted to share what was going on before it ‘gets twisted and exaggerated into something different or worse’.

Yesterday she announced her upcoming shows in Denmark, Bristol and Belgium would have to be cancelled as her recovery was taking longer than expected. "After having an operation earlier this week, I am unfortunately suffering a longer recovery time than expected due to some problems that have occurred post the operation,” she told fans on Instagram.
