Eva Longoria, Kristen Bell and more compete in Words With Friends Celebrity Challenge

Eight celebrities are taking on a cerebral challenge for charity by playing Words With Friends against each other. Organized by Edward Norton, the seven other celebs include NBA-er Paul Pierce, actress Kristen Bell, actor Jonah Hill, rapper Snoop Lion, actress Sophia Bush, singer John Legend and actress Eva Longoria.

You can help, by joining a celebrity team and playing Words With Friends now through Oct. 3. Each word you play gives your celebrity pick a chance to earn more money for their charity.

Charities include Harlem Grown, the Maasai Wilderness Conservation Trust and several more. And in case you're wondering why famous Words With Friends player Alec Baldwin isn't participating, Norton tells the AP, "Next year, for sure, if I have any say in it. I'm going to win this year, so adding him to the mix next year will make it interesting for me."
