Pete Doherty is terrified of what secrets his mother may reveal in her forthcoming book about her troubled rocker son. The Babyshambles frontman, who is battling an addiction to heroin and crack cocaine, knows the upcoming tome has the potential to seriously embarrass him. He says, "I don't know if it's a tell-all book, but I am a little bit scared. Imagine your mum writing a book. "The stories, like when I got in my sister's Brownies uniform... there might be one or two pictures. My dad was really worried. I was about nine."
