Willow and Jaden Smith have signed on as youth ambassadors Project Zambi, a global initiative dedicated to helping kids orphaned by AIDS in Africa.

Says Willow, age 8: “Even from the other side of the world, kids in Africa will know they have friends who care about them.” Her brother, Jaden, 11, wants to “represent all the kids out there who want to make the world a better place.”

A ten-day online auction of celebrity-autographed Hasbro baby elephants began Monday.

Leonardo DiCaprio, George Clooney, Scarlett Johansson, Alicia Keys, Jessica Simpson and a bunch of other celebs have also signed onto the project.
