Jessie J has revealed that suffering a stroke as a teenager was the catalyst she needed to succeed.

The popstar was diagnosed with Wolff-Parkinson-White syndrome, a heart condition that can causes an irregular heartbeat when she was nine. In her 2012 autobiography, Nice To Meet You, she explained her father, Stephen Cornish, also suffers from it.

Appearing on Australia's breakfast show Mornings with fellow The Voice Australia coach Ricky Martin by her side, the Price Tag singer attributed her ailment for her strong willed personality and determination.

"I had a minor stroke when I was 17" she told host Sonia Kruger. "The weirdest thing is being that sick made me Jessie J."

Although she was targeted the bullies after the medicine she was prescribed started turning her skin green, she refused to wallow in self pity.

Explaining the reason why she touched on her own health battles during a blind audition when wheelchair-bound Tim McCallum took to the stage, she said: "I'm very proud of myself and sometimes we have to say that and tell ourselves that. I've done a lot more than I thought I could."

"There are still moments when I have to make sure I'm looking after myself and not pushing myself too hard," the star added.

In June, the 27-year-old songstress took a musical hiatus to recovery from a mystery operation.

Sharing a snap of herself in a hospital bed, she wrote: "I don't often share personal stuff (especially about my health) anymore, I just get on with it.

"But I wanted to share with you before someone else might and it gets twisted and exaggerated into something different or worse."

Jessie is scheduled to jet Down Under later this year, to commit to her role as a coach on The Voice Australia.
