NEW YORK (AP) _ Movie star Kevin Bacon plans to marry blue-blooded actress Kyra Minturn Sedgwick in September, says a spokesman for the actor.

Publicist Allen Eichhorn made the announcement Monday.

Miss Sedgwick has been rehearsing with Jason Robards and Colleen Dewhurst in a production of Eugene O'Neill's ''Ah, Wilderness 3/8'' opening today in New Haven, Conn.

Bacon's screen credits include ''Footloose,'' ''Quicksilver'' and the recent films ''She's Having a Baby'' and ''End of the Line.'' He has also appeared on stage and television.

Miss Sedgwick is the daughter of Patricia Heller of New York, an educational and family therapist, and Henry D. Sedgwick of New York and Stockbridge, Mass., a venture capitalist. Her great-grandfather, Endicott Peabody, founded the Groton School.

Bacon's father, Edmund, is former director of the Philadelphia City Planning Commission. His mother, Ruth, teaches preschool children.

SAN FRANCISCO (AP) - It's taken most of her 68 years, but entertainer- busines swoman Eva Gabor says she has finally learned to live alone without fretting.

''The last five years is the first time I'm not married in my life, and I've found my center - a sense of self-responsibility,'' said Gabor, who is promoting her upcoming autobiography, to be published by Little-Brown.

Gabor, the younger sister of actress Zsa Zsa Gabor and the former co-star of the television series ''Green Acres,'' has been married five times.

''I enjoy, really enjoy, living alone, which is strange for a lady who was the clinging vine of all times,'' she said recently. ''I became a grown-up being, an idea I always fought, and have discovered that it's better to live alone and be at peace with yourself than to be married and to be under continuous stress.''

Besides running her 16-year-old, international wig business and tending her garden at home in Los Angeles, Gabor works for AIDS patients and cancer victims.

''To die with AIDS is to die without dignity,'' she said. ''I've seen it in my hospice work. You are treated like a leper. To me it's worse than cancer, because cancer nurses don't come into your room with masks and gloves.''

WAUSAU, Wis. (AP) - The organizer of an auction for a local ballet school says she's been overwhelmed by donations from more than 100 stars, including a pair of red dancing shoes from Liza Minnelli and a compact mirror from Ginger Rogers.

''Things are still coming in,'' Ellen Ricciardi, director of the auction to benefit the Central Wisconsin School of Ballet, said Monday. ''I have been totally surpised ... It's neat for little Wausau to get items like that.''

Proceeds from the auction scheduled April 23 will help pay for educational programs and performances, Mrs. Ricciardi told The Wausau Daily Herald. Between 100 and 200 students from preschool through high school attend the school in this central Wisconsin city, she said.

She said other items include a signed copy of a ''M-A-S-H''television script from star Alan Alda and a pewter mug from actor Paul Newman.

Jessica McClure, the 2-year-old rescued last October after spending 58 hours in an abandoned well, and Olympic gold medalist Bonnie Blair were among the newer celebrities who threw out the first pitches of the baseball season.

In Arlington, Texas, Jessica bounced a one-hopper into the mitt of Texas catcher Gshe did it twice to the roars and applause of the Arlington Stadium crowd, who saw the Rangers defeat Cleveland 4-3.

Blair, who won the gold in the 500-meter speed skating event at the 1988 Winter Games in Calgary, Canada, threw the first pitch in the opener between the California Angels and the Chicago White Sox.

The 23-year-old from Champaign, Ill., may have brought the local team luck. The White Sox beat the Angels 8-5.
