Jessie J reckons she would be up for contributing a track to the Fifty Shades of Grey soundtrack.

The singer reportedly told the Daily Star that her new found maturity means that she would be suitable to write a song for the movie version of the erotic novel.

The 'Domino' star said: “I could do the song for the Fifty Shades film. Who knows, why not?"

She continued: "I’m 25 now and I was 18 when I wrote my first album. So, however much I love Price Tag, I feel a bit childish singing it now. And that’s OK to say. I’ve grown and evolved and this new album’s more about who I’m gonna be for ever rather than who I am right now.”

The Voice UK coach also commented on her image, stating that she felt moulded by the industry when she was first starting out. Jessie J said:

"When you first start out, a lot of people control what you do. I felt I was becoming a cartoon character. I always had my own style, I’ve always known what I want to look like whether I’ve got short hair or long hair, but I was visually looking like someone else’s dream and not my own.

“Now I always do what I wanna do – but it’s a lot of work. It’s pressure to always look good in this industry, and always be on trend, but I think I look like myself.”
