James Cameron and some of the Avatar cast celebrated Earth day yesterday in a big way. The day began at the Avatar Earth Day tree planting celebration held at the Twentieth Century Fox Studio Lot in L.A. The Avatar evening celebration brought out some A-listers in celebration of the 40th Anniversary of Earth Day. The red carpet was complete with Avatars who greeted guests!
Last night also seemed to be a showcase for young hot celebs sporting new, shorter 'dos.
Adrien Grenier and Hayden Panettiere had brand new hair cuts!
Hayden proudly wore her new, drastic short look with boxing boyfriend Wladimir Klitschko at her side!
Hayden is a big advocate for environmentally friendly practices, and worked on the Oscar-winning documentary The Cove.
