Emma Stone and Hillary Clinton are pretty happy with their Billie Jean King T-shirts

As far as high-powered female Twitter trifectas go, this one is an ace.

Tennis legend Billie Jean King posted a photo of actor Emma Stone and former presidential candidate Hillary Clinton on Wednesday, featuring the pair holding up their own copies of a vintage-inspired T-shirt with King's face on it.

The pair were both guests on Wednesday night's The Late Show with Stephen Colbert and were roped into this little gem backstage:

Later on the show, Stone told Colbert she thought she "looked nude" in the photo.

The shirt Stone and Clinton are holding is a replica of the T-shirt made famous by King’s longtime mate Elton John. It shows King's face and her final score from the famous 1973 "Battle of the Sexes" tennis match.

Stone plays King in the upcoming film Battle of the Sexes, which examines the 1973 match between King, already an important women's rights advocate, and Bobby Riggs (played by Steve Carell). It's out Sept. 22 in the United States.  

A portion of the proceeds from the shirt benefit the Billie Jean King Leadership Initiative and Elton John AIDS Foundation. You can grab one via Homage for $32 — and we're guessing they'll go pretty quick with this kind of promotion.
