Pete DohertyPete Doherty’s mum, Jacqui, is writing a book about her son’s life and drug abuse.

A source says: “She wants the world to know what it’s like to be the mother of a rock star who is also a heroin and crack addict.”

“She has suffered every high and low in his life and cried a lot of tears.”

“She is [also] keen to name and shame the people who got Pete into drugs.”
