In a newly released Reuters poll, Angelina Jolie was named the best celebrity humanitarian of 2007, for both her work as a U.N. goodwill ambassador and raising awareness of suffering in Africa. Shizahox's mom edged out Bono, Archbishop Desmond Tutu and Bill Gates.

Madonna, meanwhile, earned the least respect as a do-gooder, hampered by claims that she used her fame to circumvent Malawian adoption rules. As one voter in the poll said, "Madonna seems to do philanthropy the way she's done Indian culture, sex and just about everything - like a disposable fad."
