Oprah Winfrey, Brad Pitt and Angelina Jolie top Phil’s list of Hollywood’s most generous entertainers who have used their fame and wallets to draw attention to causes ranging from poverty and genocide in Africa, to rebuilding areas of destruction caused by an earthquake in Peru and Hurricane Katrina in New Orleans.

Oprah Winfrey
Oprah has long believed that education is the door to freedom, offering a chance at a brighter future. Through her private charity, The Oprah Winfrey Foundation, she has awarded hundreds of grants to organizations that support the education and empowerment of women, children and families in the United States and around the world. She opened a state-of-the-art school in South Africa for disadvantaged girls. The $40million dollar Oprah Winfrey Leadership Academy for Girls launched at a time when HIV/AIDS, poverty and illiteracy still makes a brighter future an impossibility for the nation's young.

Brad Pitt & Angelina Jolie
Through the Jolie-Pitt Foundation, which the couple established in September 2006 as a vehicle for their philanthropic activities, Hollywood’s philanthropic couple handed over $1m to help Sudanese refugees of the Darfur crisis. The pair continued to raise funds for victims who are still in need of housing two years after Hurricane Katrina’s devastation. Through Pitt’s “Make It Right” project, he wants to rebuild a neighborhood in the particularly hard-hit Ninth Ward with sustainable green homes. He has teamed up with Matt Petersen, President and CEO of Global Green, as the lead funding partner for the Holy Cross Project. globalgreen.org

Shakira
Shakira pledged $45m during Clinton’s Global Initiative summit on climate change held in New York. Through the Latin America for Solidarity Foundation (ALAS) - which she co-founded with Nobel Prize winning author Gabriel Garcia Marquez, she will donate $40m to repair damage caused by an earthquake in Peru and a hurricane in Nicaragua. An additional $5m will go to educational projects benefiting children across Latin America. fundacionalas.org

Al Gore
When Gore won the Nobel Prize, he donated his half of the $1.56m prize to the Alliance For Climate Protection. The Alliance and Gore made the summer's Live Earth: The Concert for a Climate in Crisis, happen. The alliance’s follow-up campaign persuaded thousands of Americans to lobby Washington on global warming issues. “The climate crisis is not a political issue," Gore said in an email. "It is a moral and spiritual challenge to all of humanity. It is also our greatest opportunity to lift global consciousness to a higher level." climateprotect.org

Bono
The U2 front man spun his philanthropic energy into a new groove by becoming the first guest editor of Vanity Fair and created July 2007’s Africa issue. The issue had 20 different cover photos of high-profile individuals, all taken by renowned photographer Annie Liebowitz. He remains a leader in the fight against poverty, and has helped to create the ONE Campaign, DATA, (RED) and EDUN, a clothing company which is striving to stimulate trade with poverty stricken countries. joinred.com

Jerry Lewis
The 81-year-old veteran of movies including “The Nutty Professor” has raised over $2 billion for neuromuscular care and research. The 42nd Annual Labor Day Telethon raised a record-setting $63.8 million in donations and pledges this year alone. The 21 1/2-hour show benefited the Muscular Dystrophy Association. mdausa.org

Paul Newman
This year Newman's Own introduced two new premium organic wines to join ranks their other distinctive products. It was only 25 years ago that Paul Newman bottled his first product--a salad dressing in old wine bottles with parchment labels. Since that humble start, the line of goods has grown dramatically and generated revenue to allow Paul Newman and the Newman's Own Foundation to donate more than 200 million dollars to thousands of charities.

Steven Spielberg
He has given more than $10 million to the Survivors of the Shoah Visual History Foundation. In 2007, Spielberg donated $1 million to George Clooney's Darfur campaign. He also supports the Cedars-Sinai Medical Center, Entertainment Industry Foundation, Film Foundation, (RED), and the Righteous Persons Foundation. righteouspersons.org

George Clooney
Clooney and friends like Don Cheadle and Matt Damon are just a few of the stars that are uniting to stop the crisis in Darfur. “What we cannot do is turn our heads and look away, and hope that this will somehow disappear,” Clooney preached. “It's the first genocide of the 21st century.” savedarfur.com
