Jessie J has hit out at singers who do not write their own songs.

In an interview with Scotsman.com, she calls them "dummies":

"There are lots of artists out there who are just dummies, getting dressed by management, being told what to say and sing and wear, but I'm really proud of the fact that I write songs and pitched one to Britney. She might not have used it, but I'll just write a better one".

The 23-year-old has said that as a popstar, she has noticed that she has had to take on more responsibilities:

"It's a bit like taking on ten more jobs at the moment. I wanted to be a singer, but now I've had to become a model, a spokesperson, a good interviewee - everything".
