Leonardo DiCaprio

Why We Heart Him: He digs the environment.

We've been crushing on Leo for pretty much as long as we can remember, but it was when he started to get involved in environmental issues that we started to see him as something other than a Hollywood hottie. In an attempt to do his part against global warming, Leo drives a hybrid car, has solar panels on his house, and takes commercial flights instead of private ones. His dedication to the cause is also apparent in his feature documentary The 11th Hour, which encourages people to go green, and his plans to build an eco-friendly resort on a Belizean island. Now, that's putting his money where his mouth is!
