Charlize Theron says her 4-year-old son, Jackson, had a crush on her co-star Emily Blunt during "The Huntsman: Winter's War" filming. "My son is in love with her," she tells ExtraTV. "He thinks she's, like, the most beautiful princess ever. Yeah, it's crazy. I didn't even exist, he was just like, 'Ahhh, she's a princess.' I'm like, 'I'm a queen.' "

When it comes to his own mother who plays a not-so-nice queen Ravenna, little Jackson prefers to call her "spicy." Blunt remembers how the boy observed his mom, "He was watching her close-up and she was really going for it, like, and the intensity, and it was just one of those heightened scenes. Jackson was watching her close up and he went, 'Oooh, Mama's spicy.' "

Theron was not the only one bringing her kids to the set. Co-star Chris Hemsworth also brought his daughter and twin sons. The children ended up enjoying playdates. "There was a whole difference of energy on this because we all had our kids there on set a lot of the time," the Aussie actor explained in a previous chat with Us Weekly.

"Normally, the set being this sort of tense, respectful, quiet sort of place," he said. "That was just thrown out the window when the kids came. They were chasing each other around with the weapons and yelling, 'Get him!' 'Kill her!' 'Do that!' "
