Kate Moss and long-time beau Pete Doherty will get married this summer--on the condition that Doherty stays clean, according to the latest reports.

Pete's diaries, "The Books of Albion," were published last week, and Pete revealed several choice details about his relationship with the famed supermodel. Among them were Kate's demands that he stay clean for the wedding, the real reason the former heroin addict went to rehab (because Kate made him) and, descriptions of how the two apparently fight all the time. "Kate and I are fighting all the way on the Eurostar until blood finally runs down my palm and up my head, and before I leg it to oblivion leaving her at the station calling me a this, that and the other and a so-and-so (accompanied by hand gestures)," Pete says in the book.

Apparently, Pete is not allowed to talk about the wedding either. he is appearing on a talk show next week and sources say: "She's given him rules on what not to talk about. The wedding is absolutely off limits."
