Claudi Schiffer
Claudia Schiffer is holding off writing her autobiography because she's scared of divulging intimate details of her life.
The 37-year-old - who has graced the cover of over 550 magazines in her career so far - has turned down several lucrative publishing deals because she isn't ready for fans to learn all about her life as a model.
She says, "I've had a lot of offers but I just don't feel ready yet. Everyone writes them when they are so young these days, and I don't think the time is right for me.
"Plus you have to write about all these incredibly personal things. I've always been a very private person - but who knows? Maybe one day I'll feel ready."
