Meet Bar Refaeli, Maxim Hot 100 list no. 6
Bar became the first Israeli model to appear in the Sports Illustrated Swimsuit Issue in 2007 and graced the cover of said issue in 2009. She has appeared on Israeli TV and has guest-judged on "Germany's Next Top Model" with Heidi Klum. She is also known for her charity work with Ahava, an organization that helped abandoned pets in Northern Israel after the Israel-Lebanon conflict in 2006.
Her romance with DiCaprio started in 2005 when they met at a party in Las Vegas. It reportedly ended in 2009, but there were rumors they had started up again last year. We aren't sure of their current status.
If you'd like to see Bar in action, here is an interview with her on "The Ellen DeGeneres Show" from 2009. She seems like a sweet girl.
