DeGeneres, a New Orleans native whose 82-year-old aunt, cousins and friends had their Gulf Coast homes destroyed, has taped an episode of "The Ellen DeGeneres Show" dedicated to discussion of the devastation. It will air Monday, the start of the syndicated talk show's third season.
"We have a different show planned for you today because things have changed and we cannot pretend they haven't," DeGeneres tells the audience. "I can't pretend to do a normal show."
DeGeneres also plans to announce a hurricane relief fund. The show's producer, Warner Bros. Entertainment, said it would donate $500,000 and match viewers' contributions up to another $500,000.
Beginning Tuesday, Jay Leno will ask his "Tonight Show" guests to sign a Harley-Davidson motorcycle that will be put up for bid later this month on the eBay Internet auction site.

The Dave Matthews Band, which has played at the New Orleans Jazz and Heritage Festival, announced a Sept. 12 benefit concert in Denver.
"We're just getting in line behind those people, getting in line a long way behind the Red Cross or National Guard, but we all have to do a little bit," Matthews told The Associated Press.
E! Networks announced that it would produce a public service announcement to support the American Red Cross featuring Eva Longoria, Pamela Anderson, Destiny's Child, Steve Carell, Nicole Richie, John Larroquette, Mariah Carey, Carlos Santana and Paula Abdul.
Larroquette, a New Orleans native, said Friday he would also contribute artwork to an online auction organized by actor Morgan Freeman.
"I feel quite impotent in this situation," said Larroquette. "Since I can't get down there on the ground and help ... I just want to help appeal to people to care about people in this country as we do so generously to those in trouble around the world."
