NEW ORLEANS — Angelina Jolie and Brad Pitt used their star power Saturday to help The Children's Health Fund focus attention on the more than 46,000 children still displaced 2 years after hurricanes Katrina and Rita destroyed their homes.

Jolie said her work as a goodwill ambassador for the United Nations High Commissioner for Refugees prompted her to get involved with the CHF's effort.

"This is the largest displacement of children in my own country so I want to learn as much as possible," she said at a news conference.

Jolie said that in her travels she has seen many children who feel defeated.

The difference here, she said, is that children "are feisty, fun and full of pride. They know where they're going and what they're going to do. It's that kind of spirit that will help everyone get through this."

Pitt and Jolie have made New Orleans their home since the hurricanes and have been working to help the area recover.

Pitt has pledged more than $5 million to Make it Right, a project to rebuild 150 homes in the Katrina-devastated Lower 9th Ward, one of the city's most impoverished neighborhoods. *
