We told you before about the recently uncovered 12-hour videotape on which the hotel heiress allegedly calls two black men "dumb n-s."

Now, oil heir Brandon Davis, who reportedly was standing next to Hilton when she uttered the racial epithet outside a club, contends that she repeatedly uttered the slur.

"She was forever using the N-word," Davis, the boyfriend of "O.C." star Mischa Barton, tells The National Enquirer. "I told her not to use it. It was offensive. But she just laughed. She is a racist plus an idiot."

Davis says Hilton also "puts down Jews and other minorities, too. And I'm Jewish. I found it depressing."

Davis, grandson of oil and movie mogul Marvin Davis, has known Hilton since they were in diapers. He now tells reporter Alan Smith: "I finally had enough of her attitude six months ago.

I don't want anything to do with her."

"She is going to pay a price," he predicts. "Her value as a commodity is severely damaged."

Reps for Davis and Hilton did not immediately have a comment on The Enquirer story.

Hilton has yet to deny that she used the N-word on the videotape, but she has said in a statement, "Anyone who knows me knows that this is not me. I love everybody and am not a person who discriminates against anyone - ever."

A baldly partisan ploy

Moby isn't in the habit of selling his body, but he agreed to go on the auction block Tuesday night.

Taking the stage at a Slipper Room fund-raiser to defeat President Bush, the techno-rocker admitted: "I'm a short, bald, middle-aged guy. Why anyone would want to have a date with me is beyond me."

But he apparently looked good to three women who pooled $800 to win a meal with the Mobster at his lower East Side tearoom, Teany.

After tossing in another $800, he joined the house band on a cover of Led Zeppelin's "Whole Lotta Love."

The rave god, who who appears on Putumayo's new "Blues Lounge" CD, agreed with emcee Jay McInerney that "if you haven't made up your mind [about Bush vs. Kerry] yet, there must be something wrong with your mind."

KRS-One, decency zero

If Osama Bin Laden ever buys a rap album, he'll probably start with a CD by KRS-One.

The hip-hop anarchist has declared his solidarity with Al Qaeda by asserting that he and other African-Americans "cheered when 9/11 happened."

The rapper, whose real name is Kris Parker, defiled the memory of those who died in the terrorist attacks as he spouted off at a recent New Yorker Festival panel discussion.

"I say that proudly," the Boogie Down Productions founder went on, insisting that, before the attack, security guards kept black people out of the Trade Center "because of the way we talk and dress.

"So when the planes hit the building, we were like, 'Mmmm - justice.'"

The atrocity of 9/11 "doesn't affect us [the hip-hop community]," he said. "9/11 happened to them, not us," he added, explaining that by "them" he meant "the rich ... those who are oppressing us. RCA or BMG, Universal, the radio stations."

Parker's screed drew a loud boo from novelist Tom Kelly, who was in the audience. "I lost six friends there on 9/11," Kelly told us afterward.

Parker also sneered at efforts by other rappers to get young people to vote.

"Voting in a corrupt society adds more corruption," he added. "America has to commit suicide if the world is to be a better place."

Ex-Nirvana rocker Krist Novoselic, who was on the panel, yelled back: "That is wrong, man. Suicide is not the answer."

But, judging by Parker's downward-spiraling career, he's already bent on self-destruction.

Britney who?

Meet pop music's newest sensation - Britney Federline! Huh?

That's what Britney Spears wants to call herself now that she's married dancer Kevin Federline.

"I like that," Spears tells the German magazine Bunte. "Society probably won't allow me, but I would like to change it."

The pop princess also told the mag she's more interested in making babies than hit records. "There are a few things I want to take care of this year before I have my baby," she added. "I want to become a mother. I'm crazy about children ... next year, when I'm 23, I'll be ready."

Barry sorry, folks

Barry Manilow is begging forgiveness from gay fans.

The singer got himself into trouble at his Madison Square Garden concert last Thursday when he introduced a duet he was about to sing with Brian Darcy James, the star of his new musical, "Harmony."

Manilow told the audience that the two would sing the ballad "Every Single Day," but "we're not going to sing it to each other - because that would be creepy."

Following complaints to gay-rights groups, Manilow's rep, Jill Fritzo, tells us the line was "meant lightheartedly, but he's very sorry if he offended anyone. Barry is a longtime supporter of AIDS research and Lambda Legal Defense," a gay-rights organization.

Asked about speculation that Manilow is himself gay, Fritzo said, "I don't comment on anything personal."

Not up the creek

John Kerry may be helping keep Hollywood's red-hot lovers together.

Cameron Diaz and Justin Timberlake joined Brad Pitt and Jennifer Aniston at a Tuesday-night screening in L.A. of "Going Upriver," George Butler's acclaimed documentary about the presidential candidate's Vietnam service.

Both couples have been dogged by rumors that their romances are on the rocks. But spies tells us that each star pair looked happy and holding steady.

Also at the Director's Guild screening of the Palisades Pictures release were Catherine Keener and Dermot Mulroney, Diana Ross, Reese Witherspoon, Ed Norton, Rob Reiner and Michael Stipe.

Side dish

Rupert Murdoch must not be too vexed by "Unfit Commander," the Bush-bashing exposé that Judith Regan is using his money to put out. The conservative media mogul had a big hug for his moneymaking publisher when he ran into her at the Ivy in L.A. the other day. Sons James and Lachlan Murdoch also had kisses for Regan, whose HarperCollins imprint is celebrating its 10th anniversary ...
