Katy Perry plans to make "real f***ing dark" music now she has split from Russell Brand.

The 'Part of Me' singer ended her 14-month marriage to the British comic in December 2011 and she believes the upheaval in her personal life will inspire her to move away from her trademark pop sound and will result in her making a more introspective record.

She said: "Well, my music is about get real f**king dark. I'll be shoe-gazing. You'll never see my face because my hair is in my face."

Katy - who has previously revealed details about her private life on TV talk shows and is close friends with publicity magnet Rihanna - admits she struggles to deal with the paparazzi lens on her at all times and the constant interest in her private life.

She said: "If I decide to go out and get a coffee, and there's a paparazzi up in my face ... I can't really think of any time when I wasn't working that I ever overstepped that boundary and called them out or got into their game -because you can't control that game once you do get into it.

"But I think it's disgusting. What I wanted to be and who I am is a singer and a songwriter. I wanted to be onstage, and I wanted the world to hear my music. The product of that is fame and the disgusting celebrity that goes along with it."

Katy is willing to give herself over to the public domain when she is working, but will not do the same if she is enjoying her personal time.

She added to Interview Magazine: "When I'm working, I'm all yours. But when I'm not working, stay the f**k away. That's how it goes. So whoever made up the idea that everyone has the right to every bit of information about you because you're famous ... No one made that rule. It's not a law."
