Pete Doherty is set to dish the sordid details on his on/off relationship with Kate Moss, according to the alleged co-author of his new autobiography.

The Babyshambles frontman has apparently joined forces with former drug addict Sean Boru to write an “intensely personal” account of “the sex and drugs and rock'n'roll lifestyle” the couple shared before their split in July 2007.

Boru says, "The whole premise of the book is Pete talking about Kate Moss and the sex and drugs and rock'n'roll lifestyle they shared.

"I wrote to Pete when he was in jail about my experiences when I was a drug addict and we built a relationship.

"He knows I understand where he is coming from and this is the first book that properly details his private life with Moss - which is what everyone wants to read about."

We're sure the notoriously litigious Kate already has her lawyers on stand-by...
