Troubled British rocker Pete Doherty is planning to write his wedding banns in blood when he marries model girlfriend Kate Moss. The Babyshambles frontman, famed for his blood paintings, was reported to have turned up to an unspecified town hall in London with a vial of blood, in a bid to persuade authorities to accept his plans for an alternative marriage. But Doherty's dramatic pleas were flatly refused, and he was politely offered a pen instead. A source says, "It was explained to him that there are health and safety issues and council rules. "Pete was told that there was a selection of pens he could choose from, but he decided not to bother. He clearly lives in a different world." A friend of Doherty says, "Like any couple, they need to fill in forms to announce their intention to wed - he just came up with a twist. "He told Kate that the first official document about their union should be scrawled in his own blood so everyone knows how he feels about her."
