Brad Pitt & Angelina Jolie

As a team, actors Brad Pitt, 44, and Angelina Jolie, 32, have served as our goodwill ambassadors worldwide. They brought help to Pakistan in 2005, after a catastrophic earthquake killed tens of thousands of people and left millions homeless. They have tended to the poor and sick in Africa. And they've raised global awareness—and contributed $1 million of their own money—for the victims of atrocities in Darfur. Brad co-founded Not on Our Watch, an organization set up to focus global attention on Darfur and other hot spots.
