LOS ANGELES, April 16 (UPI) — Charlize Theron says her 4-year-old son Jackson is “in love” with Emily Blunt, her co-star in The Huntsman: Winter’s War.

The actresses play sisters in the upcoming fairytale movie.

“My son is in love with her,” Theron told TV’s Extra.

“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.’”
