"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."
Jessie J revealed she didn't cancel her upcoming concert because she believed it would help her.
"I have done 2 shows in 2 years and my soul needs it," she explained. "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."
The "Domino" singer revealed she had chosen to have a baby on her own in her emotional post.
"I decided to have a baby on my own," Jessie J wrote. "Because it’s all I’ve ever wanted and life is short. To get pregnant was a miracle in itself and an experience I will never forget and I know I will have again."
Jessie J had recently been linked to dancer Max Pham Nguyen following her split from Channing Tatum.
