In an apparent testament to the constancy of love - verily, to love's

immortality

- virtuoso artist

Pamela Anderson

, 40, and

Rick Salomon

, 39, were back together just 72 hours after Pam filed for divorce, TMZ.com says, citing an unnamed source. This means Pam's sacred union to her third hub, solemnized on Oct. 6, might just see its 73d

and

74th days!

Pam's latest soulmate Rick is the swain who marketed his XXX tape,

1 Night in Paris

, about his tryst with

Paris Hilton

. This is also his third marriage. He previously brought sweetness and light to the lives of

Marcus Schenkenberg

, Pam married refined high-society wit and noted poet

Kid Rock

Late-night hosts will return

Guess the rumors are true: Late-night hosts

David Letterman

,

Conan O'Brien

and

Jay Leno

plan to return to their shows Jan. 2, two months after they went dark as a sign of solidarity with the striking Writers Guild.

"With the New Year upon us, I am left with a difficult decision," NBC man O'Brien said yesterday. "Either go back to work and keep my staff employed or stay dark and allow 80 people, many of whom have worked for me for 14 years, to lose their jobs.

"If my show were entirely scripted I would have no choice," he added. "But the truth is that shows like mine are hybrids."

Leno said his priority was to keep his people working. "I feel it's my responsibility to get my 100 nonwriting staff, which were laid off, back to work," he said.

French prez's passion for music

He's got access to France's nuclear arsenal.

And now he also has full access to - the very soul - of that stunning-sexy-sophisticated supermodel-turned-singer

Carla Bruni

.

The brute!

That (highly cultured) brute happens to be the ruler of France, President

Nicolas Sarkozy

.

French news weekly L'Express has published photos showing the newly divorced 59-year-old politico and the Italian-born Carla, who will turn 40 on Dec. 23, out on a date Saturday.

The sighting led the Sarkozy-admiring paper Le Figaro to run this headline yesterday: "Carla Bruni: The President's Girlfriend."

So what was the new couple's hot date? A

dîner intime

at an exclusive restaurant? A quiet walk along Paris' side streets? A hot dance grind at an underground club on Place Pigalle?

Think again. The couple were at . . . Disneyland Paris. (Gotta love globalization.)

The editor of L'Express tells the Associated Press that Bruni, who has previously been linked to

Mick Jagger

and

Donald Trump

(

yikes

), has confirmed she and the president are dating.

Rihanna: Stung by rumors

Barbados-born hottie

Rihanna

- who is all of 19 - is getting tired of hearing rumors that she's dating hottie actor

Josh Hartnett

.

"This is what really happened," the chanteuse tells Allure mag. "He and my management, they have each other's contact information. I went to [the New York club] Pink Elephant, and he came by."

Simple enough, right?

But, Rihanna said, "all of a sudden, the next day, I'm seeing that we were kissing and hugging up each other."

The singer (born

Robyn Rihanna Fenty

), who made the big time with her single "Umbrella," has previously been linked to

Shia LaBeouf

and the 38-year-old superstarsupermogul

Jay-Z

(?!), who is president of her record label, Def Jam.

She has denied any involvement with Jay-Z, who is, after all,

Beyonce

's man.

2001: A Space Odyssey

author

Sir Arthur C. Clarke

, celebrated his 90th birthday - his "90th orbit of the sun" - Sunday in his adoptive home, Sri Lanka.

Sir Arthur, who has written more than 80 books and 500 short stories and essays, also has contributed to science fact. He was the first to suggest using satellites orbiting Earth for communication.

He said he had three wishes for the world. First and foremost, "I would like to see some evidence of extraterrestrial life," he said. "We're still waiting for E.T. to call us."

Clarke's second wish is for humans to "kick our current addiction to oil."

Finally, he wished peace for Sri Lanka, which has been embroiled in a decades-long civil war.
