Kate Moss "couldn't think of anything worse" than having a Twitter account.

The social networking site is used by a wealth of global stars to document the latest goings on in their lives, but Kate isn't signed up.

The stunning supermodel respects her privacy too much to have an account.

"No. I couldn't think of anything worse than people knowing what I'm doing all the time. I just don't understand it. I don't get it at all. Why would anybody want to know? I try to be the opposite, so people don't know anything that I'm doing. I don't want people to know anything!" she laughed in an interview with British newspaper The Times.

Kate is one of the most famous women in the world. Although she cherishes her super-successful career, the 38-year-old star wishes she was anonymous from time to time.

"Just to go into a shop without getting stared at would be nice. I mean, I don't walk around like, 'Oh, I'm famous' - I try to live as normal a life as possible - but sometimes it's a bit annoying. It's fine; it's not a massive problem, but sometimes it's just a bit uncomfortable," she said.

"You can't be 'poor me' about it - it's not the worst thing in the world, but sometimes it's a bit uncomfortable."

Kate also broached the subject of writing a biography. The beauty hasn't shied away from scandal throughout her career, and says people would love to know what she has to say about her personal life.

"No. Not until I'm, like, 105. Because you can't get a good book unless you're going to spill the beans, and I can't spill the beans... not for a long time. It's got to be a good book if you're going to do it," she smiled.
