Don't believe AV. He takes some perverse pleasure in giving this answer to any such question. I don't know her name but she's really rubbish (if very pretty) - probably a model who does a bit of speaking rather than a proper actress.
Not everyone has a perfect memory like you AV - some of us see someone that we recognise but can't place them, and trying to remember who they are nags away in the mind until we get an answer or it fades away. Asking on ANSWERbank is one way of nipping it in the bud (but you are already aware of all this, you just like being perverse).
