Does green clash with pink?

Paris Hilton apparently doesn't think so.

An insider says the heiress is learning how to be eco-friendly from her new friend, "Entourage" star Adrian Grenier.

"He's helping her pick out a home that she can easily convert into an environmentally friendly living space," the source tells E! Online's "Planet Gossip" co-host Tina Dirmann. "Adrian has really been teaching Paris a lot about what people can do to help the environment and to just live their lives in a more 'green-friendly' way because it's a cause he's very involved in, and, so far, Paris is listening."

The actor reportedly thinks that the heiress can do a lot of good if she goes green.

"Adrian told her, 'You're the most photographed woman in the world. Think what you could do if you used that attention to bring light to a cause.'" the source added.
