Jessie J was inspired to write a song about the recent London riots after the studio she was in had to be evacuated. 

The 'Nobody's Perfect' hitmaker was working on a track yesterday, August 9, but was disrupted by the continuing violence, rioting and looting in the capital and explained to her fans on Twitter that her original plans had to be changed because of what was happening outside:

"Im off to the studio. If I cant help physically. Im going to write about it. I have broken my ankle and Im on crutches, which is why I said I am going to write if I cant go out. Thats how I help. I write songs. Go easy on me man. I didnt mean it no ignorant way, thats not who I am."

"I was writing a song but I had to leave as the studio was evacuated.."
