Jessie J once wrote 150 songs in two years.

The 'Do it Like a Dude' hitmaker has a prolific output as a songwriter, but that doesn't mean her path to the top has been easy and she admits luck hasn't always been on her side.

She told "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."

Jessie, 23, has started writing her second album already and is planning for it to reflect how she has grown since she became famous.

She added: "I think the next album will be all about maturity and how I have grown a lot. My whole life has changed and obviously I know that there's a lot of people that can't relate to the life I live.

"However there are a lot of people who can relate to the challenges I have been set and the craziness that you see."
