Charlize Theron went head-to-head with Josh Hartnett in a hilarious game of Tonight Show charades on Tuesday, May 20—and revealed that her son Jackson is currently obsessed with princesses and Tinkerbell!

In a move that will no doubt make little Jackson, 2, blush in years to come, mom Theron dished to Jimmy Fallon that her little boy, like other tots worldwide, can't get enough of Frozen and other Disney heroines.

"He's really into princesses now," the South African actress shared. "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!"

Charlize then joined her Tonight Show co-stars in an amusing game of charades, teaming up with Steve Higgins to take on opponents Fallon and Hartnett.

The Snow White and the Huntsman actress rose to her charade challenges impressively, leaving host Fallon to discover that Tina Turner's "Private Dancer" was a tough song to act out.
