The 24-year-old actress dropped by the Tonight Show Starring Jimmy Fallon Tuesday to promote her upcoming movie Camp X-Ray, Because the film is "very serious [and] very dark," Jimmy decided to "lighten the mood a little bit" with some elephant face masks and a rousing game of "Ring Around the Nosey."
"It's the most fun game ever," said the late-night host. "Every kid is playing it right now. Pokemon, then 'Ring Around the Nosey'...You're just going to love it, Kristen, I swear! You'll just get so happy when you put it on."
