British star Sienna Miller has hit back at claims she's addicted to media attention, insisting she's only seeking publicity to promote her new movie FACTORY GIRL. The 25-year-old actress was mocked by the British press for appearing at the Factory Girl New York premiere after party in a pair of knickers last week (ends03FEB07) - but Miller insists being in the spotlight is "all part of the job". She says, "Look, I'm doing all this PR for a movie that's coming out. It's a big publicity push. I have to do it. It's part of my job. But I don't read all the stuff. I don't keep it, I don't cut it out or save it or look at it or stick it in scrapbooks. "If I were the type who'd be reading all about myself, I'd be quite sick of myself."
