Added Spice?: The Spice Girls said Monday that they may add “two new members to the Spice family”--a statement that didn’t quite confirm published reports that two members of the British pop group are pregnant. News reports have said that Posh Spice, Victoria Adams, is expecting a child with her soccer-star boyfriend, David Beckham, and that Scary Spice, Melanie Brown, and her boyfriend, dancer Jimmy Gulzar, are also expecting. A statement released by the group’s publicists said: “We are sisters and love each other, and love being together as a band and as friends. We plan to continue on, perhaps adding two new members to the Spice family. Until such a time as we are sure of our news and ready to make a statement, we would like to appeal to people to give us privacy during this time.” The Spice Girls’ U.S. tour is scheduled to wind up Wednesday in Dallas.

Beck, Devo Headline Show: Beck and Devo will headline Silicon Planet, a technology and pop culture exhibition tour that includes an Oct. 17 stop at the Santa Monica Airport’s Barker Hangar. David Spade of the NBC sitcom “Just Shoot Me” will be the host of the event, which also features a Calvin Klein fashion show and new technology displays and demonstrations. Other dates are Oct. 3 in San Jose, Oct. 10 in Seattle and Oct. 24 in Austin, Texas, with part of the proceeds benefiting AIDS-related charities. Silicon Planet, which founder Tom Hayes calls a celebration of “the digital lifestyle,” began last year as a single event in San Jose. Tickets for the Santa Monica show, at $100 for regular admission and $45 for a limited number of student tickets, will go on sale Sunday.

The Carrey Show: The red leather jacket with sequined decorations was vintage Elton John, but the guy wearing it was . . . Jim Carrey. Midway through his Saturday concert at the Arrowhead Pond of Anaheim, Sir Elton welcomed the comic superstar to the stage, and the pair ripped into a duet of “Rocket Man.” The crowd went wild as Carrey matched John’s rock wail with an impressive voice of his own. The cheers turned to laughter when Carrey sat beside John at the piano for some four-handed accompaniment, but used his head instead. As Carrey exited the stage, John said, “Whoo, boy--I won’t forget that one.”

Comic Soundtrack: With movie soundtracks making it big on the pop charts these days (witness the recent success of the “City of Angels” and “Armageddon” collections), the genre is branching out, with DreamWorks Records set to release the first soundtrack album for a comic book. Titled “Songs of the Witchblade: A Soundtrack to the Comic Book” and due in stores Sept. 8, the album features a narration by actor Eric Bogosian and includes songs by Babes in Toyland, Megadeth, Skinny Puppy, Dave “Rave” Ogilvie and former Nine Inch Nails member Chris Vrenna. Also in the works is an upcoming live-action TV movie based on the “Witchblade” series, scheduled to air on TNT in January.

PEOPLE WATCH

Lennon Autograph Won’t Benefit Killer: The deranged fan who killed John Lennon doesn’t want a cent for the Lennon album he got the rock star to autograph shortly before the murder. Lennon signed and dated the “Double Fantasy” album for Mark David Chapman outside his apartment building the same day he was killed, Dec. 8, 1980. The record is being offered for an asking price of $1.8 million on the Internet by an anonymous man who found it at the crime scene. Chapman, who is serving a 20-years-to-life prison sentence in Attica, N.Y., said he was contacted last week by a New York City lawyer who told Chapman he had the legal right to “assert a claim” to the album as a personal possession. “I have no interest whatsoever in making a claim” for the album, Chapman told the Rochester (N.Y.) Democrat and Chronicle. “I have never profited from this crime, and I never will. I hope the money will be donated to charity.”

QUICK TAKES

Plenty of seats remain for “Back to Titanic Live in Concert,” Oct. 9-10 at the Hollywood Bowl, after tickets went on sale Monday. “Historically, classical concerts don’t sell like shows by Bruce Springsteen,” said promoter Andrew Hewitt. “But, in nautical terms, we haven’t hit an iceberg. We expect a slow, steady sale.” . . . Due to financial restrictions in its native Brazil, the band Karnak has canceled its scheduled appearance on Thursday at the Santa Monica Pier. The Los Angeles swing bands Alien Fashion Show and Flattop Tom & His Jump Cats will replace the group at this week’s edition of the weekly Twilight Dance Series. . . . A benefit screening of “Big Wednesday” on Wednesday at the Santa Monica Civic Auditorium will mark the 20th anniversary of the release of the surfing film and will raise funds for the Surfrider Foundation. . . . Teen country star LeAnn Rimes returned to the concert stage Saturday in Columbus, Ohio, after canceling three shows last week because of a respiratory infection. . . . Fans of ABC’s gritty TV crime drama “NYPD Blue” weren’t the only ones surprised by ABC’s casting of former child star Rick Schroder, 28, to replace Jimmy Smits. “I feel like I won the lottery,” the former “Silver Spoons” star told the New York Daily News.
