While they have been mum about their relationship in the past, they have since made their love public. Nina's in very good company — Ian has dated some lovely ladies in the past, and we've got the photographic evidence. Warning girls: It may be hard to enjoy these photos with another woman dangling from Ian's arm, but he always looks nice regardless.
