CAMERON DIAZ - DIAZ HELPS PROMOTE 'LIVE EARTH'

DIAZ HELPS PROMOTE 'LIVE EARTH'

Cameron Diaz has joined forces with former US vice president Al Gore to promote a new environmental awareness initiative.

A 24-hour global event, Live Earth, will start on July 7th and will be similar to Bob Geldof's Live 8 concert.

Massive concerts will be held on every continent – yes, even Antarctica – with Snoop Dogg, Kelly Clarkson and Lenny Kravitz already confirmed to play at the super-gigs.

But there was no mention of Cameron's ex- beau Justin Timberlake strutting his stuff to save the world.

The In Her Shoes star told the audience at the California Science Centre: "This is the only issue in the history of mankind that affects every single one of us - our planet is in danger. But at least someone is doing something about it."

And it seems the 34-year-old actress is greener than most. Speaking at the announcement's press conference, the blonde-bombshell was keen to promote a more eco-friendly approach to life in Hollywood: "I've been driving a Prius since they came out. I carbon neutralize when I travel. I recycle."

The actress, added: "If we can get people to change one aspect of their lives, even do one thing, that's a step closer."

Could Cameron be the greenest girl in Hollywood?
