Cameron's Eco Romance

Cameron DiazCameron Diaz gave her tuppenceworth at Live Earth last week.

The environmentally conscious star gave tips on how to save the planet.

But she recently admitted being too "selfish" to really stick to greener plans such as reducing her carbon footprint.

In The Green Book - The Everyday Guide To Saving The Planet One Simple Step at a Time, the Shrek beauty is quoted as saying: "I don't want to be running around barefoot, pushing my car like Barney Rubble.

"I don't want to go back to the Stone Age. I'm very selfish."

But perhaps contrary Cam is trying to make up for such non-PC statements...

As she has since been spied on a date with wealthy British environmentalist, David de Rothschild.

Do you think Al Gore set them up after Cam's uncaring slip about global warming?

Perhaps Dave is explaining to her just how important it is to do a Barney Rubble.

The couple reportedly met at the Live Earth New York's VIP area, before heading out on a date together later in the week.
