GOOD MORNING: “There is no antibiotic for it,” Carrie Fisher admitted. The “it” is showbiz and Carrie said after her mom Debbie Reynolds invites Carrie’s daughter Billie (4) on stage in Vegas, the youngster will be afflicted with showbiz the rest of her life — as were her mother and grandmother! Reynolds calls the youngster “Miss Abba Dabba Jr.” (Grandma sang “Abba Dabba Honeymoon” in “Two Weeks With Love”) Apparently there is also no antibiotic for Debbie’s problems with husbands. She was in court again this week and Tuesday afternoon won a judgment against her most recent husband, Richard Hamlett “for mismanagement of my pension assets,” said Reynolds. “The judge ruled in my favor.” She had previously won a judgment against Hamlett for $8.5 million in the divorce suit Debbie’s previous marriages to Harry Karl and Eddie Fisher were also financial fiascos, you recall. … Reynolds celebrates her 65th birthday at her Las Vegas hotel April l. It won’t be a TV spectacular, as was Elizabeth Taylor’s 65th, but Reynolds’ showroom will be packed (582-seats) with well-wishers from L.A. and Vegas. Some of them will put on a show for her after Debbie does the first show that night, reports son Todd. It’s hoped Debbie’s mother Maxine will be able to be on hand. She celebrates her 85th birthday Friday and is now recuping at St. Joseph’s Hospital after fracturing her elbow Monday. … Reynolds attends the Oscars escorted by longtime friend Jerry Wunderlich, three-time Oscar nominated set decorator, who also designed the Acad’s Board of Governors’ Ball at the Music Center and Shrine seven times. … Sherry Lansing accompanies husband Billy Friedkin to Florence Friday when he starts researching to direct the German opera “Woyzeck” by Alban Berg there next March. Zubin Mehta will conduct. It’s Friedkin’s first opera and he admits he has no musical background “whatsoever.” But he’s studying German now. The 1913-set story is about jealousy, revenge and murder — “Just my thing,” Friedkin laughed. He wound MGM TV-Showtime’s “12 Angry Men” in 12 days and “under budget,” he added.THAT’S SHOWBIZ, TOO: Natalie Cole gave her all, singing a complete concert (gratis) as Anne (Mrs. Kirk) Douglas was recipient of the Women of Courage Award at the SRO BevWilshire ballroom. Not only that, Cole also bought a table for $10,000 as her contribution to the Cedars-Sinai Research for Women’s Cancers recipient of the $1.2 million raised Monday p.m. … Jay Leno, who motorcycled (wearing his tuxedo) from Burbank to hilariously m.c. the evening, also produced a $5,000 check from his pocket and offered to contribute it to the charity if “Melrose Place’s” beautiful Lisa Rinna (seated with fiance Harry Hamlin ) would come on stage to give him a kiss. Of course she did. Leno told me, “I was going to give the check anyway, but I thought I would do it in a little silly way.” The audience loved it and him. David Foster and Warren Weedy also delightfully duetted. Gregory Peck, who made the presentation to Anne D., said it was “a great pleasure” as he enumerated her many contributions to the hospital and to the less fortunate in all areas of the community — a remarkable “record of achievement by a woman with a big heart.” She said, “When Irving Feintech (chairman of the 21st Century campaign) asked me to accept the ‘Women of Courage’ award, I assumed I was getting it for having been married to Kirk for 43 years.” She admitted, “Twenty-five years ago I was diagnosed with breast cancer. At that time there was no such thing as a lumpectomy, let alone alternative therapies. A mastectomy was the only option and there was little understanding of how to deal with the devastating effects. Today, thanks to people like Dr. Beth Karlan, women who are challenged by cancer are offered far superior alternatives and treatments. There is healing now for the mind as well as the body.” Husband Kirk and son Peter were among all giving her a standing ovation. Sandra Krause, Marion Laurie, Margie Petersen and Renette Ezralow chaired. ADD TO THE HEFTY OSCAR ACTIVITIES this weekend: a two-day seminar hosted by Sherwood Oaks College, with Anthony Minghella, Brenda Blethyn, Scott Hicks, Armin Mueller-Stahl and Lynn Redgrave at the Ivar theater in Hollywood. … Adrienne Barbeau and husband-producer Billy Van Zandt welcomed identical twin sons, Walker Steven Barbeau Van Zandt and William Dalton Barbeau Van Zandt, born Monday in L.A. It’s a first for them, but Barbeau has a son from a previous marriage. … Kym and Jerry Douglas are expecting their first child Sept. 14. She’s on E! Entertainment’s “Gossip Show”; Jerry’s a 15-year “Young & Restless” co-star. … Lynda Jamison, the “middle-aged Cinderella” success story who SRO’d at her CineGrill stand, is now booked for Mother’s Day at Maxim’s in N.Y. … The Karl Maldens, Hume Cronyn and Elia Kazan dined at Dan Tana’s “and talked the history of the business,” laughed Malden. Kazan’s here to visit son Nick.
