Charli XCX says it's unfair that successful women are always accused of being bitches.

But Charli insists there are always question marks against high achieving women and a presumption they must have a tough attitude to have got where they are.

In an interview with the Metro newspaper, she said: "When it comes to being a successful woman, there always seems to be a question. 'Why are you successful? Is it because you're a bitch?' There always seems to be a negative connotation.

"There are only a few female ex ecs at record companies. There are a lot of great female songwriters and producers, but they're definitely a minority, especially on the business side."

Charli is one of the most outspoken and outrageous pop stars around and she doesn't plan on changing because all the artists she loves had a rock 'n' roll attitude.

She explained: "I've never tried to be anything that I'm not and sometimes that gets me into trouble with things I say because I'm outspoken. I grew up wanting my rock stars and musicians to be rock stars and musicians, not super tame and vanilla. I like true artists and it's sad that we've lost so many icons this year like Prince and Bowie, they were kick-a**."
