AMELA ANDERSON

is getting divorced from husband No. 3. No, she's not. Or maybe she is.

But we bet she will, sooner or later.

A nasty fight supposedly led the double-threat talent to file divorce papers last Thursday against husband Rick Salomon, several Daily News sources reported early yesterday. You remember Salomon, don't you? His big claim to fame - er, make that slightly larger than average - was his notorious sex tape with Paris Hilton.

But Pam and Rick apparently have made up, and all is forgiven.

"P.S. We're working things out," Anderson coyly shared in the diary on her official Web site, though she didn't get specific. And reports of the divorce filing in Los Angeles continue to clog our in-box.

Pam's been married to rocker Tommy Lee, with whom she has two sons, and to rapper Kid Rock. Her marriage to Lee lasted three years; the Kid Rock hook-up survived three months.

Salomon and Anderson wed in October, but their union might have to last a season. US Weekly reported last week that the couple are working on a reality TV show for E!

Anderson's denied that, though.

While meticulously researching this important story, we pored through Anderson's official bio, wherein she talks about the character she played on Fox's "Stacked" - "a woman tired of living the fast life and making bad choices in boyfriends who takes a job at a bookstore."

Pam should try that on reality TV.

One size fits all?

Aw, Judd Apatow, you shouldn't have.

Come Friday, we're heading to the multiplex to unwrap the lovely gift he's giving us girls via (we presume) John C. Reilly and other male stars of his new film, "Walk Hard: The Dewey Cox Story."

"It's Christmastime and it's my present to America - an enormous amount" of nudity, particularly male nudity, Apatow revealed at the film's premiere, reports the New York Daily News. "It's about time we saw some naked men. It shows I'm not sexist."

Added Reilly, "We're very proud; there are a lot of c---- in this movie."

Back to black . . . for good?

Amy Winehouse wants to kill herself. Having watched her descent from talented singer to self-destruction-as-art-form, this comes as no surprise.

But we are surprised that, along with the sickening excess of drugs and booze, the hive-haired warbler (and Grammy nominee) has found another way to get herself in a world of trouble.

The New York Post reports cops are eyeing Winehouse in an alleged plot to bribe a witness in the assault trial of her husband, Blake Fielder-Civil. Winehouse has reportedly said that if both were to receive lengthy jail time, they'd make a death pact.

He's already in jail, awaiting trial with another man on charges of savagely beating a bartender in London last June. Not too civil, is he? At least Amy takes her name seriously.

Childhood's end

Science-fiction writer Arthur C. Clarke has turned 90, and he marked the occasion Sunday by asking for three simple gifts: increased use of clean energy sources; lasting peace in Sri Lanka, where he's lived since the '50s; and solid evidence of extraterrestrial beings. Guess he wouldn't be satisfied with the naked girls in "Walk Hard."

The British-born author, who moved to Sri Lanka in 1954, has written more than 100 sci-fi books, including "2001: A Space Odyssey" and one of our personal faves, "Childhood's End."

"Sometimes I am asked how I would like to be remembered,"

Clarke said during the small celebration in Colombo. "I have had a diverse career as a writer, underwater explorer and space promoter. Of all these I would like to be remembered as a writer." *
