Paul Newman was the most generous celebrity of 2008.

The late 'Cool Hand Luke' actor - who passed away last September - donated more money to charity than any other US star, giving a huge $21 million to various initiatives and campaigns, according to a list compiled by The Giving Back Fund for Parade magazine.

Also included on the list of most generous celebrities are Angelina Jolie and her partner Brad Pitt, Mel Gibson and Oprah Winfrey.

Angelina and Brad spent an estimated $13.4 million on good causes including a health clinic in Ethiopia and the redevelopment of New Orleans last year.

The couple also donated $1 million to help children caught up in the Iraq conflict, through education programmes via their Jolie-Pitt foundation.

Upon donating the money, United Nations ambassador Angelina said: "These educational support programmes for children of conflict are the best way to help them heal."

Brad added: "We hope to encourage others to give to these great organisations."

Meanwhile, Mel invested $6.5 million to causes including a Holy Family Church in California and Oprah created scholarships for kids in the hometown of her longtime partner, Stedman Graham.
