Julia Roberts Gets On The Bus

The biodiesel-fueled bus that is. The pretty woman will be helping biodiesel producer Earth Biofuels promote a program to encourage the use of biodiesel in more than 500,000 diesel school buses nationwide. A recent addition to the Earth Biofuels board of directors, Ms. Roberts will serve as a spokesperson for the eco-fuel. ''It's very important that we expand our use of clean energy and make a long-term commitment to it. Biodiesel and ethanol are better for the environment and for the air we breathe,'' Roberts said in an announcement about her new role. She will be joining current Earth Biofuels celeb board members Willie Nelson and Morgan Freeman. ::Via Hugg Photo from Vanity Fair
