Kate Moss has cancelled plans to write a tell-all autobiography about her drugs scandal and her relationship with junkie rocker Pete Doherty.

Moss decided to open her heart after she was photographed in a British newspaper appearing to snort cocaine.

But she has changed her mind after the police decided not to prosecute her.

Public relations expert Mark Borkowski says: "The book deal was a wise move at the time, but it's a wiser move now to pull out as she has got her career back on track. She is perceived to have cleaned up her act.

"So she can save the memoirs for a rainy day when she needs to re-invent herself."
