Putting their money where their mouths are! In addition to walking the red carpet and living the glamorous life, these celebrities, including Angelina Jolie, Lauren Conrad, and Matt Damon, are working hard to make the world a better place. Read up on their charities!
Holly Robinson Peete
Actress Peete supports Children Mending Hearts, a charity that facilitates arts education programs for disadvantaged kids. "I'm in my 40s and can't remember any class where there wasn't art. We didn't do it just to finger-paint -- it develops your brain," says Peete. "My daughter is lucky to go to schools where there is a lot of art implemented, but the children that are missing out on those programs are missing out on an important part of their development. We have to change that."
