It's that time of year again! All year long, we tell you stories of celebrities who go above and beyond to support their causes by donating time and of course, money. Who are the most generous of these stars? The Giving Back 30 by The Giving Back Fund spells it out for us, listing the top thirty most generous celebrities of 2008.

The number one spot was claimed by the great Paul Newman, who passed away in September of 2008. The late actor donated over $20 million last year to various organizations benefiting the environment, education, health, human services and more. The humanitarian power duo Angelina Jolie and Brad Pitt came in a close second with over $13.5 million in donations, followed by Mel Gibson who gave $6 million to various organizations and churches.

Other top contenders were Richard Childress ($5 million), Oscar de la Hoya ($9.5 million) and Oprah Winfrey ($2.4 million).

What's up, Oprah? The media mogul topped last year's list with a heavy $52 million given to charitable organizations in 2007. Maybe she gave all her money away! Unlikely.

Regardless, each celebrity named is worthy of praise for their extreme generosity and kindness towards those in need.

Who do you think will top the list next year?
