SCREEN ACTORS Guild President

Alan Rosenberg

said yesterday that members of the smaller AFTRA actors union should reject a proposed contract deal with Hollywood studios because a better deal could be had.

Rosenberg made his comments at a rally staged as the guild tried to reach its own deal with the studios.

SAG previously asked the American Federation of Television and Radio Performers to delay a membership vote on its proposed deal, but AFTRA refused.

SAG said that a delay would help it negotiate a better agreement.

Rosenberg told the crowd of several hundred people at the rally that it was "essential to vote down that AFTRA deal."

About 44,000 actors belong to both unions.

The move prompted AFTRA to warn that it might pursue legal remedies if SAG tried to "undermine or interfere with our ratification process." AFTRA members are set to vote on the three-year contract later this month.

SAG's talks with the Alliance of Motion Picture and Television Producers entered the 25th day yesterday. Contracts with both unions expire June 30.

Rosenberg told members Sunday that gains sought for actors in areas such as DVD and new-media compensation were not achieved in the AFTRA contract.

Pam prize on auction block

"Baywatch" babe Pamela Anderson is selling her prized, customized 2000 Dodge Viper and donating the proceeds to People for the Ethical Treatment of Animals.

"I've been working with PETA for 15 years," Pam told the Associated Press. "They're kind of my ethical advisers. With them, I see actual results."

The Viper has a prominent role in Pam's forthcoming E! series, "Pam: Girl on the Loose," but she admitted that it was dangerous for her to own such a high-performance vehicle.

"I'm a terrible driver," she said. "It's just not a good idea for me to have a Viper."

The car will be among the offerings at Julien's Auctions' Summer Entertainment Sale of Hollywood memorabilia, June 21 and 22 at Planet Hollywood in Las Vegas. Other items will include Alfred Hitchcock's driver's license, personal snapshots of Marilyn Monroe and Sammy Davis Jr. and an original "Ben Hur" script signed by Charlton Heston. The sale will be broadcast live on Auction Network.

Tattle stork

Jessica Alba and her husband Cash Warren are new parents.

Jessica, 27, gave birth to a healthy baby girl, Honor Marie Warren, on Saturday, her publicist Brad Cafarelli said yesterday. Cafarelli didn't provide further details.

Alba and Warren wed last month after becoming engaged in December. They met on the set of the 2005 film "The Fantastic Four," which costarred Alba. Warren was a director's assistant and proved again that it's OK to sleep with the people you work with, if one of them is Jessica Alba.

Jason Rothbart, at your cervix

While awaiting delivery at Cedars-Sinai Medical Center in L.A., In Touch Weekly reports that Tori Spelling is seeing Angelina Jolie's OB-GYN.

Tori was scheduled for a C-section at 3 p.m. (Pacific Time) yesterday, one week before her due date, an anonymous insider told In Touch.

Dr. Jason Rothbart, Angelina's doctor, was to perform the surgery.

Rothbart delivered Tori's toddler son, Liam Aaron, and is expected to leave for France to handle Angelina's twins. He previously delivered Shiloh in Namibia.

How would you like to go into labor and find your obstetrician is in Namibia because, face it, your baby just isn't that important.
