Celebrity Largess

Teen pop star Hilary Duff pledged $250,000 for relief. Rock star Dave Matthews is throwing a benefit concert. And Oscar-winner Nicolas Cage donated $1 million to the American Red Cross. Celebrities are coming forward in droves to pledge help for victims of Hurricane Katrina. We wondered whether this has a ripple effect among fans.

Psychologist Stuart Fischoff of Psychology Today magazine says yes, celebs can inspire fans to do things they might not do on their own: "As many celebrities as possible should get out there and show something positive."

However, he says he isn't convinced that all of the personalities have the right motives and said some are just "looking to resuscitate their careers."

Manhattan-based psychiatrist Spencer Eth says he is equally skeptical: "It's a good career move for them."

Regardless of motives, artists helping out include:

* Rapper Master P and son Romeo -- New Orleans natives -- plan a "Save Our Hood" concert and album.

* The Dave Matthews Band plans a Sept. 12 concert at Denver's Red Rocks Amphitheater, with all proceeds going to relief.

* Rap mogul Diddy and self-proclaimed "greatest rapper alive" Jay-Z have pledged $1 million to the American Red Cross.

* Celine Dion and the partners of her Las Vegas show pledged $1 million to the Red Cross.

* Country singer Alan Jackson plans to donate all proceeds from his Sept. 8 show in Columbus, Ohio, to the Red Cross. He'll also perform with Keith Urban, Alison Krauss and Craig Morgan in the telethon "Country Reaches Out: An Opry Benefit for the American Red Cross" on Sept. 27.

* Rapper Juvenile, who lost his brand-new home and "everything" in the storm, encouraged fans to donate to the Red Cross.

* Kentwood, La., native Britney Spears has not pledged financial support for victims, but posted a message on her Web site saying her "thoughts and prayers go out to everyone" in the affected areas.

Eth says it's important for celebrities to step forward to help a cause -- but they need to stick with it.

"This is going to take months and perhaps years for the affected communities to heal," he said. "If celebrities can stay with the program, that would be ideal, rather than moving on to the disaster of the week."

Fats Domino Resurfaces

R&B legend Fats Domino, reported missing after Hurricane Katrina destroyed his home, has been sleeping on a couch in the two-bedroom Baton Rouge, La., apartment of LSU starting quarterback JaMarcus Russell, The Post's Eli Saslow reported yesterday.

"We've lost everything," the 77-year-old said. "I don't know what we're going to do."

Domino and his family were rescued by boat late Monday night, then taken to a shelter in Baton Rouge. Domino called Russell, whom he had met just once before. Russell gave shelter to more than 15 people after Katrina.

"Without JaMarcus, it would have been even worse," said Domino. "We can't thank him enough for letting us stay."

He added: "I'm worried about all the people in New Orleans. Tell them I love them, and I wish I was home with them."

Domino left Russell's apartment yesterday afternoon with his wife, two of his daughters and a son-in-law. He said he had no idea where he would go next.
