Unfortunately for Sienna Miller, she happens to be a gorgeous woman in a profession of many gorgeous women, which may explain why we may forget about her from time to time. Today is all about Sienna, though, because it's the UK actress' birthday. If you need a quick refresher, she's the sex-goddess from Layer Cake who was also dragged into the News of the World phone tapping scandal. I can say without a doubt that her club scene in the Daniel Craig gangster-flick is the sexiest thing I've ever seen smoking (below). Her photos aren't chopped liver either. Check out her hottest photos below.
