PALM SPRINGS (AP) – Former tennis great Billie Jean King plans to design a tennis and fitness center for the area’s first gay, lesbian, transgender and bisexual retirement community.

King won a record 20 Wimbledon titles and four U.S. Open championships, and beat Bobby Riggs in a nationally televised showdown billed as “The Battle of the Sexes” in 1973 – a triumph that brought attention to women’s sports.

She came out as a lesbian in the 1980s, causing her to lose endorsement deals.

Plans for the community are expected to be submitted to the city in May, with groundbreaking to take place early next year.

“This will be a fun place to live and be healthy,” King said as she announced her plan to design the Billie Jean King Fitness & Tennis Center for the project. “It’s about the body, mind and spirit – the whole person.

“You don’t have to be alone when [you] get older. There’s a sense of safety and hope and choice.”

King is the only woman to win U.S. singles titles on all four surfaces – grass, clay, carpet and hard – and was the first female athlete to earn at least $100,000 in prize money in a single season.
