Charlize Theron Tests Out her Charades Chops with Josh Hartnett on "Tonight Show"

During promotions for "A Million Ways to Die in the West," Charlize Theron stopped by "The Tonight Show Starring Jimmy Fallon."

While sitting down with the hilarious host, the Oscar-winning actress chatted about her darling son Jackson, 2, and his new interest in Disney princesses.

"He's really into princesses now," Charlize explained. "He's got a real love for this Tinkerbell doll. Sometimes Tinkerbell has to take a trip, just to give his other toys a chance. Tinkerbell goes to Africa a lot!"

Meanwhile, Miss Theron joined Jimmy and his partner Steve Higgins for a fun game of charades. In need of another hand, Jimmy brought Josh Hartnett onto the NBC stage to take part in the festivities. Check out their antics below!
