LONDON (AP) _ Conductor-composer Leonard Bernstein was awarded the Royal Philharmonic Society's 73rd gold medal, joining such musical greats as Johannes Brahms, Jean Sibelius and Sergei Rachmaninoff.

Composer Sir Michael Tibbett presented the award to Bernstein on Sunday after the 68-year-old American conducted the Amsterdam Concertgebouw Orchestra in works by Franz Schubert and Gustav Mahler at Barbican concert hall.

Bernstein is touring Europe with the Dutch orchestra.

Other recipients of the medal include Pablo Casals and Igor Stravinsky.

WIMBLEDON, England (AP) - West German tennis star Steffi Graf has rejected a $270,000 offer to pose nude for Penthouse magazine's German edition, saying she prefers Centre Court to the centerfold.

''I really laughed about it. I was really surprised that someone could get the idea to even think about it,'' the 18-year-old Graf said Sunday. ''It's ridiculous, strange.''

Graf, ranked No. 2 in the world, advanced Saturday to the fourth round at Wimbledon by beating Laura Gildemeister of Peru 6-2, 6-1 at Centre Court.

Carlo Frey, the magazine's publisher, said the whole world would be interested in the photos.

''She's now 18. She is without doubt Germany's most popular young lady,'' he said. ''Everyone knows what she's like on a tennis court, but no one knows what she's like in private.''

CUMMINGTON, Mass. (AP) - Red-faced town officials say they'll apologize to Secretary of State George Shultz for the publicity that erupted when they asked for help to end nude bathing in a swimming hole near his weekend retreat.

''It started as just a local selectmen's meeting, and then it got out and bango 3/8'' Monica Vandoloski, chairwoman of the Board of Selectmen, said Saturday. ''We really just wanted to die.''

Selectmen in this small town about 100 miles west of Boston said swimmers were crossing Shultz's land to reach Caulker's Pond, a secluded, state-owned cove on the Westfield Branch River where many swimmers do so in the buff.

Last week, the selectmen asked Shultz to post no-trespassing signs on his property, but the move got more publicity than they expected.

Selectman Dennis Forgea said the board planned to write Shultz a letter of apology. ''He's got more important things to worry about,'' Forgea said.

LOS ANGELES (AP) - As Prince Charming and the seven dwarfs looked on, Snow White got a star on Hollywood's Walk of Fame honoring her half-century as an animated character.

Sunday's ceremony was held in anticipation of the July 17 re-release of ''Snow White and the Seven Dwarfs,'' Walt Disney's first full-length animated feature.

''I look at the film and it is just as good now as then,'' Roy Disney, the Disney studio founder Walt's younger brother, told the crowd.

The actress playing Snow White, who was not identified, posed with her star along with her dwarfs and thanked everyone for their support.

She arrived in a carriage drawn by two horses, but her departure had a touch of the Eighties. Snow White left in a white stretch Cadillac limousine.

LOS ANGELES (AP) - Comedian Martin Short has made three movies back-to- back, including the new release ''Innerspace,'' but the ''Saturday Night Live'' star says he can take or leave films.

''I'm not like this guy who would sell his soul to do a movie,'' Short said in a recent interview. ''I love television.''

Television is more immediate than film and ''also doesn't take itself so seriously,'' he said. ''It's tough with films, when the budgets are high and the stakes are high.''

Short said doing ''Innerspace,'' ''Three Amigos'' and the unreleased ''Cross My Heart'' has been interesting, ''but I'm not obsessed with these films.''
