AceShowbiz - Natalie Portman was left red-faced at the Environmental Media Awards on Saturday, October 16 after organizers aired a clip of her singing about recycling when she was just 11 years old. The actress was presenting a prize at the ceremony in Burbank, California when footage of her as a youngster, dancing and singing about the benefits of recycling, began to roll.

Portman laughed off the embarrassing gag and went on to hand the EMA Corporate Responsibility Award to Jeff Skoll, producer of "The Cove" and environmental movie "The Crazies". Veteran Hollywood star Jane Fonda also showed up to honor her ex-husband Ted Turner for his foundation's work in stopping female genital mutilation, reports Eonline.com.

The ceremony, which pays tribute to TV and films with a positive environmental message, also saw James Cameron's "Avatar" win the top movie prize. Hit sitcom "30 Rock" and TV drama "Bones" were both honored for episodes which tackled conservation themes, while HBO documentary "Gasland", about natural gas drilling in the U.S., was also celebrated.
