Rather than glitz and glamour a number of Hollywood's most prestigious stars are focusing on their environmental responsibility in the run-up to this Sunday's Academy Awards ceremony.
Actors including Leonardo Dicaprio and Penelope Cruz attended a pre-Oscars party, which, fittingly, featured a green rather than red carpet, this week in order to raise environmental awareness and funds for action group GlobAl Green USA.
DiCaprio has said that he is "proud" to help educate the public on green issues while Cruz, who co-chaired the party, warned that global warming is "threatening us all".
"Fortunately, there are many simple things we can all do such as driving greener cars or changing to compact fluorescent light bulbs, which can dramatically save energy and reduce global warming pollution," she added.
Maroon 5 performed at the party, which was also attended by Orlando Bloom, Kirsten Dunst, Ryan Gosling, Diane Kruger and Marcia Gay Harden.
As well as partying their way to environmental goodness, a number of stars are set to arrive at the prestigious awards ceremony in eco-friendly hybrids and electric sports cars instead of the traditional stretched limousines.
One of the stars who is set to arrive in such a vehicle is Orlando Bloom, who told reporters at the party that he is also making his new home as environmentally friendly as possible.
"It's as green as I can make it," he said.
In previous years stars arriving in eco-friendly vehicles include Penelope Cruz, Salma Hayek, Susan Sarandon and Harrison Ford.
The Oscars ceremony will take place this Sunday at 17:00 local time (midnight GMT) and will be hosted by comedienne and chatshow host Ellen Degeneres.
