Kate Moss has her lawyers busy trying to gag her drug-addict ex-boyfriend, Pete Doherty. The Babyshambles frontman is negotiating with Britain’s ITV2 network to tell all about their romance and share his home videos of her in a documentary titled “Kate & Pete: A Love Story.” Doherty, who split with Moss last summer, could make $1 million, a source said, adding, “Producers hope he’ll let them use a lot of film he and Kate shot on camcorders.”
