They may be super-rich stars, but Brad Pitt and Angelina Jolie never stop giving back. The celeb power couple granted $1 million to help displaced people in Pakistan in support of the U.N. Refugee Agency. Angelina, a UNHCR Goodwill Ambassador since 2001, has visited the war-torn country three times. "You go to these places, and you realize what life's really about and what people are really going through," the actress has said of her experience working with world refugees. "These people are my heroes."
