Sienna Miller and Rhys Ifans played down speculation about their relationship at the premiere of her new movie INTERVIEW on Thursday night (18Oct07) - by dodging questions and avoiding paparazzi getting shots of them other. The Alfie star arrived separately from Ifans and refused to answer any questions about whether they are dating. She even pretended not to know the Notting Hill actor was even attending the event. When asked about Ifans, the former model feigned surprise asking, "Is he here?" The pair have previously denied being involved romantically despite being photographed sharing a passionate kiss last weekend (13Oct07).
