Singer Justin Timberlake has topped The Daily Beast’s year end list of celeb philanthropists. His work for a Children’s hospital has an annual impact of more than $9 million which is much more than Madonna's $5.5 million for Raising Malawi and Pamela Anderson's $4.8 million for PETA. Bono, Angelina Jolie, Rihanna, George Clooney, Salma Hayek and Shakira also made it into the top 10.
