Despite a denial from Pittsburgh's least-favorite person, the New York Daily News' Rush & Malloy column is standing by its reportage that Sienna Miller and Hayden Christensen actually had sex on camera for the Edie Sedgwick biopic Factory Girl, in theaters today. "We freeze-framed the movie's hot spots (as rigorous journalism demands)," says the Friday column, "and there's no question Sienna and Hayden are deep into their roles." Since the News' first account hit print, Miller ( when asked in front of her folks, mind you) refuted the tale, her publicist pegged it as "not true at all," and a spokesperson for the studio deemed it "ridiculous."
