WATCH: Charlize Theron’s Son Thought Emily Blunt Was the Real Elsa from ‘Frozen’

Don’t get between a child and their Disney princesses.

The Huntsman: Winter’s War may be a spin-off of Snow White, but it’s a totally different Disney princess Emily Blunt is being compared to. Blunt stars in the film as the icy Queen Freya, but her ice blonde locks and blue and white gowns have her being compared with Queen of Arendale, Elsa. “I knew the moment I decided to have white hair that that would be the comparison,” the actress admitted to Jimmy Kimmel.

While Blunt is embracing the comparisons, there was at least one person who couldn’t tell the difference between Queen Freya and Queen Elsa. “Charlize’s son was on set a lot and he was obsessed with Frozen. He really thought I was Elsa,” she said of her costars son. Blunt kept up the charade that she was indeed the “Let It Go,” queen, but Charlize Theron’s 4-year-old Jackson soon realized the truth and he was absolutely heartbroken.

“He got really disappointed because he saw me in my sweatpants one day with the white hair on,” Blunt told Kimmel. “He just looked at me and he goes, ‘Put on your dress.’ He was really bummed about it. ‘Put it on now.'”
