The British singer said she suffered several heartbreaking setbacks when she first started out, and even lived out of her car so she would be free to go and work wherever she was needed.
Talking to website That Grape Juice, she explained: 'I think back to the early days. Days of wanting to be signed, then getting signed with a girl band, writing 150 songs in two years only for the label to go bankrupt. It hasn't been easy. I got signed to Sony as a songwriter doing support stuff in any place I could around the world for free. All the while, I was just living in a car. Doing all of that stuff that felt so crazy at the time. Yet, these are the things you have to go through to be the kind of artist you want to be. The type of artist who survives in this industry.'
