It was a star-studded event on Saturday night at the Live Earth benefit in East Rutherford, New Jersey.  Al Gore had one of his biggest supporters, environmentally friendly Leonardo DiCaprio on hand.

Cameron Diaz and Rosario Dawson got chummy at the event.

Kanye West, Sting and The Police, and John Mayer all gathered backstage at Giant’s Stadium before the big show.

Fall Out Boy Pete Wentz looked thrilled to be there.

Talk to the hand Zach!

There was a performance by the unlikely duo of Keith Urban and Alicia Keys.

I don’t think they had quite the turn out they were hoping for.

Stop blushing Cameron, the secret’s out!

Only a woman in love glows like this. It didn’t take long for Cameron Diaz to find a new hot beau to replace ex-Justin Timberlake.

They’re bringing sexy back! Yes that is Al Gore and Cameron Diaz. Hollywood’s hottest new couple has been spotted canoodling all over Tinseltown.

Whispering sweet nothings in each other’s ears…

Talk about a PDA-a-thon. Geez! Get a room already you guys!!!

Just kidding. As shocking as this sounds Al Gore and Cameron Diaz are not a couple. They were together only to announce a “Save Our Selves” campaign at the California Science Center yesterday.

Does this photo scare anyone else? This was taken in Tokyo today where Al Gore did press for “An Inconvenient Truth”.
