This weekend marked the third time Pam Anderson wore white as she pledged to stick with the same guy until she drops dead, although it was probably the first time she made that promise with a fake wedding cake.

E! Online's Marc Malkin says the oddly optimistic bombshell's Las Vegas nuptials to Rick Salomon on Saturday night were so last minute that wedding planners at the Mirage Hotel & Casino were forced to make do with a cardboard four-tier confection after an edible one couldn't be located in time.

The macromastic bride, 40, shoehorned herself into a white Valentino minidress (in -- oy -- denim), while the groom, 38, best known for his unparalleled night-vision performance in Paris Hilton's sex tape and his brief stint as Mr. Shannen Doherty, donned a black suit and his most formal black skullcap.

Anderson's attire was a definite upgrade from the white string bikini she wore when she wed Tommy Lee in 1995 and the white string bikini she partied in shortly after swapping vows with Kid Rock in Saint-Tropez last year.

She reportedly walked down the white rose-bedecked aisle in the backyard of one of the hotel's ultra-exclusive private villas to the strains of Sade's "By Your Side."

The happy couple, who we hope against hope will stay away from all video equipment during their honeymoon, exchanged vows in front of about 40 guests, including her two sons with Lee, Brandon, 11, and Dylan, 9, illusionist Hans Klok, whose Sin City magic act Anderson stars in and -- random celebrities alert -- Tobey Maguire and Lukas Haas.

OK! says Pam and Rick didn't exchange rings, which isn't surprising given that the top-heavy actress recently declared her finger would remain band-free because she believes engagement sparklers are "bad luck ... through experience!"

While she didn't receive a diamond from Lee (they opted for tattoos of each other's names -- oops), she did get a canary yellow doorknob from Kid Rock, who is still awaiting its return.

"Maybe she'll send my half-a-million-dollar ring back now," the bitter rocker kvetched to Newsweek when asked about her nuptials. "I doubt it, but, boy, that would be nice."

As the newlyweds enjoyed their first dance to Alicia Keys' "No One," well-wishers noshed on a high-class spread that included pigs in a blanket, mac and cheese, tuna and lobster tacos and jelly donut holes, which they washed down with 10 or so bottles of Cristal champagne, according to Malkin.

The festivities wound down about 90 minutes after they began because Anderson was due back at Planet Hollywood to perform her second show of the night with Klok (the wedding took place between performances).

In a recent blog posting, Pam laughed off concerns about her sudden decision to tie the knot with the upstanding Salomon by reminding everyone that he's been "a friend for 15 years."

"I don't have to defend myself. It's laughable," Pam wrote hours before she got hitched. "The greatest revenge is true happiness."

By the by, the entry was romantically titled, "The Adventures of Scum and Pam Have Begun," with "Scum" apparently being her pet name for her new hubby. And no, we don't think that's a good sign.

Another less-than-encouraging sign: Their unorthodox courtship, which Anderson told Ellen DeGeneres began as a way to pay off a gambling debt.

"I was playing poker one night in my room and I was down about $250,000, [so] he said if I made out with him, that I could clear [my debt]," she explained. "So a couple of days went by, he followed me around like a puppy dog ... and then I fell in love and now we're engaged!"
