Jessie J has said that she is "overwhelmed with sadness" as she revealed she'd suffered a tragic miscarriage after "deciding to have a baby on her own".

The 33-year-old shared two photos. One of herself holding up a positive pregnancy test as well as an emotional quote on her Instagram page yesterday evening.

In her caption, she explained how she had been nervous about keeping her pregnancy a secret.

The singer wrote: "  Yesterday morning I was laughing with a friend saying 'seriously though how am I going to get through my gig in LA tomorrow night without telling the whole audience I am pregnant'.

"By yesterday afternoon I was dreading the thought of getting through the gig without breaking down. After going for my 3rd scan and being told there was no longer a heartbeat  

"This morning. I feel like I have no control of my emotions. I may regret posting this. I may not. I actually don't know. What I do know is that I want to sing tonight. Not because I'm avoiding the grief or the process, but because I know singing tonight will help me."

She added: "I have done two shows in two years and my soul needs it. Even more today. I know some people will be thinking she should just cancel it. But in this moment I have clarity on one thing. I started singing when I was young for joy, to fill my soul and self-love therapy, that hasn't ever changed and I have to process this my way.

"I want to be honest and true and not hide what I'm feeling. I deserve that. I want to be as myself as I can be in this moment. Not just for the audience but for myself and my little baby that did it's best. I know myself and I know I would talk about it on stage because that's who I am. So instead of a tearful emotional speech trying to explain my energy. This feels safer."
