Two incredible women saluting another feminist icon. #LSSC is proud to welcome these three tonight (even if one of them is only appearing via t-shirt.) 💅🎾🙌

While backstage of The Late Show, Emma Stone ran into Hillary Clinton and together they held a shirt displaying Billie Jean King. But when she came out, she told Stephen:

“I get a chance to meet Hillary Clinton, which is unfathomable and incredible, and I look nude in them.”

“Really? You have one shot,” she quipped. “Whatever.”

Haha! Nude or not, she looks great, right? I wish I looked that great nude.

On gaining 15 pounds to play Billie Jean King in Battle of the Sexes: “For the first three weeks, you hate your life, and I know a lot of people hate exercising. I did. And then after three weeks when you’re like, ‘I can lift this? I can do this?’ It just becomes addictive. It’s just really incredible to feel strong. It feels so good.”
