Katy Perry Disgusted By Fame - 'A By-Product Of What I Do'

Pop star Katy Perry despises the fame her chart success has brought her, insisting it's a "disgusting by-product" of what she does.

The Firework hitmaker has endured a tough few months following the breakdown of her 14-month marriage to comedian Russell Brand in December and she admits she's sick of critics commenting on her personal life.

She tells Teen Vogue magazine: "I'm tired of being famous already! But I'm not tired of creating. Fame is, I think, just a disgusting by-product of what I do.

"It's quite a delicate creature - it's a wild animal of sorts. It can love you, and then it can attack you... But really, I stopped focusing on what other people think a while ago. If you try to be everything to everyone, you'll only end up completely confused."

Perry admits she wants to continue to be "as approachable and relatable as possible", but she can't understand why some devotees break down in tears when they meet her.

She says: "When I meet fans and they're crying, I'll say, 'Calm down, there's nothing to cry about. I'm not going to bite you or attack you or grant you three wishes. Let's just hang out and have a good time.'"
