- She captured 12 singles titles, 16 women’s doubles titles, and 11 mixed doubles titles (Official website of Billie Jean King).
What is Billie Jean King’s net worth?
While exact figures are not publicly confirmed, King earned $1,966,487 in career prize money (National Women’s History Museum). Her endorsements and business ventures add to her wealth, but no official net worth is available.
What is Billie Jean King’s age?
Born November 22, 1943, King is 80 years old as of 2024 (Official website of Billie Jean King).
King’s 39 Grand Slams are not just a number — they represent a career that spanned the transition from amateur to professional tennis, during which she drove the creation of the WTA and equal prize money at the US Open.
The implication: King’s fame rests on both her on-court dominance and her off-court fight for equality. She didn’t just win — she changed the system.
Does Billie Jean King have a wife now?
Who was Billie Jean King’s lover?
King’s long-time partner is Ilana Kloss, a former professional tennis player. They have been together since 1971 (National Women’s History Museum). Prior to that, King was married to Larry King from 1965 to 1987.

Ilana Kloss was born in 1956, making her 13 years younger than King, who was born in 1943. The exact age difference is 13 years.
King’s relationship with Kloss, though private for many years, became public after she was outed in 1981 — an event that cost her endorsements but solidified her role as an LGBTQ+ icon.
