Julia Roberts

Actress Julia Roberts has added her name to a growing list of celebrities and politicians who are supporting a proposal aimed at taxing oil to fund alternative energy research.

Roberts along with her husband Danny Moder toured the Mattel Children's Hospital at the University of California at Los Angeles on Monday while urging the public to vote for the proposal, known as Proposition 87, in the November 7 elections.

"We're all victims of this state's tragically poor air quality. California has the worst air pollution in the nation," TMZ.com quoted her, as saying.

After the speech, Danny was seen applauding his wife, before making his way through the crowd of photographers to personally congratulate her. The two then headed back out onto the campus of the UCLA Medical Centre. (ANI)
