I approve of this post
After months and months of waiting, everyone's favorite holiday is just a few days away - that's right, we're talkin' Earth Day! To pay tribute to this momentous annual occasion, we thought we'd post a few pix of some of our favorite treehugging celebrity friends - including a few folks whom you might not expect to catch with their arms around a redwood!

Leo's such a committed environmentalist that he's made it a policy to fly commercial flights instead of on private jets to save fuel and cut down on pollution - so cross your fingers next time you've got a plane trip in your future!

Salma Hayek's always been vocal about saving the world - even before she was bringing another child into it!

Natalie Portman is an avowed earth-lover - and we're all avowed Natalie-lovers!

How could we leave a hippie like Matthew off this list?

Don't forget - that's a hybrid car Cameron's climbing into!

Kirsten Dunst loves to keep it green - and not just in the way certain interviews she's given might lead you to believe!

Don't let the orange shoes fool you - Pierce Brosnan is green through and through!

Even Gwynneth gives it up for Earth Day!

Daryl Hannah's been a green-thumb for longer than some people in this post have been alive!
Merry Earthmas, everybody!
