Paris has decided to save the world...one tree at a time! She and her sidekick Tinkerbell, with help from her new BFF "Entourage" star Adrian Grenier, have decided to "go green." Apparently, Adrian is a vehement defender of the planet and believes that Paris can really help the cause. He's teaching her about all things "green" in the hopes that the bizarre media fascination with the heiress and....well that's about it actually, just heiress - will bring more attention to environmental causes . After all, Paris did promise Larry King that she was a changed woman after her stint in the clink...maybe this is her calling. Just not sure if green is really Tinkerbells' color!
