Felicity Jones Shows Off Her Beyoncé Dance Moves on 'The Tonight Show' - Watch Here!

Felicity Jones stopped by The Tonight Show Starring Jimmy Fallon on Thursday night (December 20) and revealed what she would do to channel Ruth Bader Ginsburg in her new biopic, On the Basis of Sex!

The 35-year-old actress had a video question come in from her co-star Armie Hammer, who asked: “Was there anything you did to prepare for these scenes?”

“I mean mostly we were just trying to, you know, loosen up. You want to be easy before you’re doing a scene as the formidable wonderful R.B.G,” Felicity revealed. “So one of the things we would do is we would watch Beyoncé videos. So we would watch a video of her doing ‘Single Ladies‘ and try really, really badly to dance follow the dance moves.”

“It’s the best way to just completely kind of, you know, it sort of just relaxes you. It just stops you from being too self-conscious,” Felicity expressed before getting up and showing off her moves – Watch below!
