Jacqueline Kennedy Onassis doesn't often take public stands, but yesterday she joined television journalist Bill Moyers in speaking out against a pair of towers, 68 and 58 stories respectively, planned for Manhattan's Columbus Circle. They charge that the towers would cast a shadow over the south end of Central Park and increase congestion. "It's time to stop the overbuilding in New York City by drawing the line at Columbus Circle and reducing the size of the monstrous building that's being proposed for there," Onassis said yesterday at a New York news conference. The former first lady will serve as chairwoman of a coalition of organizations that have united to stop the project. Onassis was involved in a successful fight in 1978 to save Grand Central Station as a landmark building.

Moyers, once an aide to President Lyndon Johnson, said, "Central Park is the people's park ... It does not belong to the highest bidder." He criticized the process by which the city agreed to sell the site of the New York Coliseum for $455 million plus $40 million in subway station improvements to the developer of the towers, Boston Properties, led by Mort Zuckerman. Zuckerman was not available for comment. The future primary tenant is to be the giant investment firm Salomon Bros.

Athanasia Georganas, a belly dancer at Georgetown's Moroccan restaurant Dar Es Salam, was under intense pressure Wednesday night. She knew that top officials of the Bolshoi Ballet were in the audience carefully watching her performance. There were Viktor Tikhonov, director of the Bolshoi; Andrei Petrov, administrative choreographer; and a 71-year-old retired prima ballerina known only as Madame Ulanova. The Bolshoi is planning a new ballet of "Scheherazade" that will have a belly dance sequence. After Georganas' performance, the Bolshoi officials asked the dancer to come to their table, where they specifically wanted to know if her dance movements were choreographed or improvised. Georganas told them she mostly just goes with the music ...

There he goes again. Actor Sean Penn, already in a lot of trouble for his ill-mannered, boorish behavior and facing a 60-day jail sentence for parole violation, was involved in a scuffle Wednesday on his return to Los Angeles from West Germany. A camera crew photographing his arrival said a shouting and shoving match ensued between the crew and Penn and his bodyguard at the door of an elevator at an L.A.

Royal Watch: Poor Fergie. Prince Andrew had intended to give her a ranch mink coat with a painted phoenix on the inside as a gift for their first wedding anniversary, but sent it back under pressure from animal rights activists.
