SIENNA MILLER and RHYS IFANS played down speculation about their relationship at the premiere of her new movie 'Interview' on Thursday night - by dodging questions and avoiding paparazzi getting shots of them other. Er... except this one.

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?"

Oh give it up Sisi, it's flamin' obvious you're in lurve, we've seen you walking your dogs with him and everything.

Oh, AND you were papped sharing a passionate snog last weekend. Error!
