Who is Bar Refaeli?

I was thinking about the previous post and thought I would find out a little bit more about who exactly Ms Bar Refaeli is. It turns out that Israeli born model Bar Refaeli is a force of beauty to be reckoned with. The 25 year-old was the cover model for Sports Illustrated Swimsuit Issue and is dated Leonardo Dicaprio. Is there any famous model this guy hasn't dated?
