Normally, pretty-boys should be seen and not heard, but when someone is as passionate about going green as Adrian Grenier, we can't help but be even more obsessed!

The Entourage charmer even paused his talk with paps (which covered everything from "green gifts" to documentaries to politics) to take a picture with a fan. And when we say "take" a picture, we mean not only did Adrian pose, but he even snapped the pic himself!

Sigh.
