Emma Stone Attends the US Open With Billie Jean King, the Tennis Pro She Plays in Battle of the Sexes

Emma Stone had the cutest date when she attended the US Open in New York City on Saturday — '70s tennis star Billie Jean King! The actress, who portrays Billie in the upcoming film Battle of the Sexes, couldn't have looked more excited as she watched the women's final on day 13 at — wait for it — the Billie Jean King National Tennis Center. In addition to Emma snapping photos of Billie, the two cheered from the stands and also posed for photos with champion Sloane Stephens.

Battle of the Sexes tells the true story of Billie's 1973 tennis match against Bobby Riggs. After spending years away from the sport, Bobby claimed he could still beat any woman, saying women belonged "in the bedroom and the kitchen" instead. The event, which was the most watched televised sports event of all time, ended with Billie completely demolishing Bobby. Long story short, any man who thinks they're better than women can sit the f*ck down.
