Although it's only been five weeks since Sarah, the Duchess of York, was in the United States, she's back again, but this time with her husband Prince Andrew.

The couple, who arrived in Los Angeles yesterday to take part in UK/LA '88, a three-month British arts festival, will make their first public appearance today at Los Angeles City Hall. A trip to Chinatown is also planned.

During their 10-day visit the royal couple will attend exhibitions and concerts related to the festival and make trips to nearby schools and churches. One thing sure to please the two licensed pilots is lunch aboard the U.S. aircraft carrier Nimitz.

After a week of L.A. festivities, the duke and duchess will pop off for two nights to Palm Springs as guests of Walter Annenberg, the former U.S. ambassador to Great Britain.

The fun, fun, fun doesn't stop there, though. After returning from California, Fergie will fly to Switzerland for a 12-day skiing holiday with her sister-in-law, Princess Diana, and the future king of England, Prince Charles.

Amy Carter's Endorsement

Amy Carter has taken up a new political interest -- Jesse Jackson. Carter spoke on the steps of the Georgia Capitol in support of the Democratic presidential candidate's campaign. "He's the only candidate who's good on women's issues," Carter said. "He's the only candidate who talks about justice for the Palestinians and justice in Nicaragua. He's the only candidate who supports gay rights and he's the only candidate that talks about South Africa at all." Jackson had nice things to say about Carter in return, praising her for "her commitment to choose the human race over the nuclear race."

Tribute to James Stewart

Nancy Reagan says she had a "huge crush" on actor James Stewart when she was young and now says the crush has grown into "a real love" for Stewart and his wife Gloria. The first lady's tribute to Stewart climaxed a salute to the actor in New York Thursday night -- an affair that doubled as a benefit for the American Museum of the Moving Image opening in May at the Kaufman Astoria Studios in Queens. Others paying tribute to the film great were Kirk Douglas, Janet Leigh, Christopher Walken, Richard Dreyfuss, Brooke Shields, Jose' Ferrer, Ben Gazzara and Farley Granger.

Tracy Scoggins Assaulted in Elevator

Tracy Scoggins, who played Monica Colby in "The Colbys" on TV, was attacked in an hotel elevator in El Paso, Tex., police said yesterday. A unidentified man was arrested at the hotel on a charge of attempted sexual assault after the Thursday night incident, police said.

Cassini's Track Record

Fashion designer Oleg Cassini redeemed himself as a professional harness racing driver when he rode a 10-to-1 shot to victory Thursday at Freehold Raceway in New Jersey. Cassini, 74, said in the winner's circle, "I feel great ... I am very happy to show everyone that I can be competitive." Cassini, who finished last in his first race Wednesday, was thrown from his sulky in the second race and was barred from the final race after a track physician said the designer's blood pressure was too high.
