Jaden & Willow Smith Support Project Zambi

Will Smith and Jada Pinkett-Smith must be so proud!

The A-lister's kids - son Jaden, 11, and daughter Willow, 8 - are serving as youth ambassadors of Hasbro's Project Zambi, Us reports.

The Smith siblings, both actors, are supporting Project Zambi to help raise awareness for the 15 million children who have lost parents and relatives to the AIDS epidemic in Africa. Jaden, who is currently filming Kung Fu Kid in China talked about his reasons for joining this great cause:

Willow and I joined Project Zambi to represent all the kids out there who want to make the world a better place," Jaden said. "We want to encourage kids everywhere to lend a hand and join us in spreading the word about how much children who have been orphaned by AIDS in Africa need our help."

Jaden and Willow have joined other celebrities in autographing custom-designed, one-of-a-kind collectible elephant models that are available in a celebrity charity auction. All funds will be donated to a charity that supports children orphaned by AIDS in Africa.

Willow described their charity of choice, The Chikumbuso Women and Orphan's Project in Zambia.

"Project Zambi is about kids and for kids, and it's so important that we all learn to take care of each other," Willow stated. "Even from the other side of the world, kids in Africa will know they have friends who care about them."
