Julia Roberts and Jimmy Fallon throw balls at each other on The Tonight Show (VIDEO)

Julia Roberts was the inaugural guest for a new game on The Tonight Show starring Jimmy Fallon called 'Face Balls'.

OMG. This game.

I love Julia so much. She was such a sport! She and Jimmy threw plastic balls at each other then they replayed the result in super slow motion.

"This is like the comedy version of Fifty Shades of Gray," said America's Sweetheart.

This is so hilarious. I cannot stop LOLing.

Jimmy said that Julia was a champ for doing it. I agree! I love her.

Julia stars in The Normal Heart on HBO.
