Sienna Miller, Edie Sedgwick in the upcoming biopic about the Warhol superstar, has, according to reports coming out of England, eschewed Jude and stolen her Factory Girl costar, Star Wars vet Hayden Christensen from his girlfriend of seven years, Lola Skye. To make matters more inflammatory, the girlfriend, who’s been with Christiansen since she was 14 and who had leukemia for years, was recovering from a bone marrow transplant when the two actors began their “sex-crazed fling.” The story comes from the British tab News of the World, but does appear to be supported by photos. That’s Christiansen and Skye hugging on the left at the airport and Christiansen and Miller on the right snogging in a car, looking just short of sex-crazed.
