HE'LL ALWAYS HAVE ROBIN

A mere six weeks ago, he was with her at the birth of their second child, Jack. But six weeks is an eternity in show biz. JOANNE WHALLEY KILMER filed for a divorce from her husband VAL KILMER on Friday, citing irreconcilable differences. Through her lawyer, Dennis Wasser, who's also representing Diandra Douglas in her split from Michael, Whalley Kilmer said she "hopes to work out all the issues involved in the marriage amicably." The "issues" include Jack and three-year-old daughter Mercedes, as well as the not inconsiderable proceeds they earn from their trade, he most notably in Batman Forever, she in Scarlett. Whalley Kilmer is asking for custody of the children.

SEEN & HEARD

After getting the better of Mothra, King Ghidorah, the Smog Monster and Megalon, to name but a few, GODZILLA is to be put down. Toho Co. will lay the lizard to rest after his 22nd movie, Godzilla vs. Destroyer, due in December. A Toho producer said there were "no more ideas left."

In other behemoth news, MARLON BRANDO has announced that he "is seriously contemplating Irish citizenship." The star, currently filming in a village in County Cork with Johnny Depp and Debra Winger, said he had "never felt as at home in a place as I do here." Although the O is at the wrong end of his name, Brando claims Irish blood via his grandmother.

MATTY 4 PREZ

Political uberconsultants JAMES CARVILLE, Democrat, and MARY MATALIN, Republican, have the highest hopes for their newborn, Matalin Mary Carville (Matty to you). "Announcing the birth of the first woman President," said a release from Equal Time, where Matalin is co-host. The parents are listed as "campaign co-chairs," and Matty's party affiliation is a "no comment." Oh, that Beltway humor.

WHO'S THE RUDEST OF THEM ALL?

There are not many people who can make COURTNEY LOVE look polite, but SINEAD O'CONNOR managed it last week -- albeit only momentarily -- when she abruptly pulled out of the Lollapalooza tour. The Irish singer announced her withdrawal in a letter to tour organizer Perry Farrell and another to the press, saying she was pregnant, and "it's hard to sing when you want to throw up all the time." O'Connor, who had been a tour favorite, also slammed reports that she was booed off the stage on a previous visit to the U.S. Meanwhile, Love, who's also on the Lollapalooza tour, roared back. Having already insulted fans of another band, she was ordered to appear in court to address allegations that she punched singer Kathleen Hanna of Bikini Kill in the face on July 4.
