Emily Blunt is on thin ice with Charlize Theron's son Jackson.

The actress plays Freya, the Ice Queen, in Universal Pictures' The Huntsman: Winter's War. Ahead of the film's Friday release, Emily appeared on ABC's Jimmy Kimmel Live! Monday and acknowledged that her character looks like Elsa, the animated queen from Disney's Frozen. "I knew the moment I decided to have white hair that that would be the comparison," the 33-year-old actress said. "Charlize's son was on set a lot and he was obsessed with Frozen. He really thought I was Elsa."

Emily didn't have the heart to tell Charlize's 4-year-old son the truth. After he accidentally caught her out of costume, he demanded she change. "He got really disappointed because he saw me in my sweatpants one day with the white hair on," Emily told Jimmy Kimmel. "He just looked at me and he goes, 'Put on your dress.' He was really bummed about it. 'Put it on now.'"

Who could say no to a cute request like that?

Emily loved putting on her character's costumes.

"It's very transporting," she said. "You do feel like you could rule the world."

Emily is used to being around kids, and later this year, she and John Krasinski will welcome their second. Their 2-year-old daughter, Hazel, isn't ready for a sibling, however. "Is she exited about having a new baby? She quite likes being top dog at the moment, I think," Emily said. "I broached it with her and the first response when I said, 'You know, Hazel, there's a baby in there; you're going to be a big sister,' [did not go well]. She looked at me and she went, 'Nope. And I went, 'Yes.' That was the first talk. We bought her every 'I'm a Big Sister' book out there."

The actress is trying to prepare Hazel to the best of her ability. "People say the relationship between you and your first child is the one that changes the most, because they've got competition. I was like, 'OK, well, I have lots of time now,' so I do lots of things with her. I was thinking, 'I'll have baths with her and stuff'...We have many baths together. I thought that I was not yet at the point where my body was just really embarrassing to my child. You know when you become a teenager and you see your parents naked and you're like, 'Ahh!' It's like the worst thing in the world. So, I got into the bath with her and she looked at me and she goes, 'Whoa! Mama big!'" Emily said. "I went, 'We are never bathing together again. That's it!'"
