King received the Legion d’Honneur from French President Emmanuel Macron at Élysée Palace on Friday in honour of her fight for women's sport, gender equality and the rights of LGBTQ people in sport.
On the 50th anniversary of her sole Roland-Garros triumph, King has been bestowed another honour.
In a nod to her trailblazing fight for gender equality, she will become the first woman to present the Coupe des Mousquetaires to the men’s champion on Sunday.
While grateful for the platform she has gained as a Grand Slam-winning great, one thing stands tall about being Billie Jean King.
“Everything is relationships,” she said. “I got to see (former rival) Françoise Durr this year, I got to see people I really care about and love. That's everything.
“It's really about the relationships, not how many titles you have won.”
