Naomi Campbell is preparing to pen an autobiography. "Oprah Winfrey wants to help me write my memoirs, so I'm going to do it with her. I love her. Only I know the truth and I will be very frank about myself. I've always said I make mistakes and that's how I learn in life. I want the people who read it to find something - whether it's just one line of help, or identification with what I've been through," she says.
