white Nokia Lumia 920. Perhaps, like many thespians do, she would like to be behind the camera some day as a director. If so, it looked like she was practicing during the Dior show by taking some video with the 8MP camera on the back of the phone. It is a great promotional shot for Nokia even if it wasn't planned.
Standing next to her was another famous actress, Sigourney Weaver, who, like the rest of the attendees pictured, did not have a phone in her hands. We're wondering if a smartphone is "alien" to her.
