Earth 101 for Paris

Paris Hilton is the new Al Gore.

The newly short-tressed socialite's been hanging with hunky "Entourage" actor Adrian Grenier, who has taken Paris under his environmentally-friendly wing.

"He's been kind of like a mentor to me, teaching me about the environment and what I can do," said Paris. So that's what they've been doing!

"I think it's cool to talk to someone in L.A. who has more to talk about than all this artificial crap people talk about. It's nice to talk to someone who's real," she said of Grenier to People. Has hell frozen over?
