Kristen Bell Cracked This Dirty Joke in a 'Frozen' Song and No One Noticed

It's no accident that a NSFW joke ended in a “Frozen.”

Kristen Bell, who voiced Princess Anna in the 2013 Disney animated film and its 2019 sequel, recently explained the story behind the double entender in the song “For the First Time in Forever.”

The 44-year-old actress gave an interview with Vanity Fair where she recounted the scene from “Frozen” where Anna sings, “For years I've wandered these empty halls / Why no ballrooms?

“How did we get this joke in there?” Bell asked aloud in the video released Tuesday.

“We kind of dropped it under the radar,” he shared “It almost didn't get in. But then we were like, 'What are you talking about? It doesn't mean anything. Don't be unreasonable.'

The “Nobody Wants It” star then explained how she had “dreamed” of being in a Disney animated movie before she starred in “Frozen.”

“They're very powerful in your life when you're young and I was obsessed with them,” Bell said. “I remember sitting in my living room and on my little boombox, like I was recording 'The Little Mermaid' when I needed a tape.”

“When I finally got the chance, I was thrilled,” added the mother of two.

Bell said that once she got the part of Princess Anna, she initially thought she would “do anything” that Disney “asked me to do”.

“But what I should try to do heroically is create a character that I needed to see when I was 11, someone like this character,” he explained. “Thanks, they let me do it.”

Bell said she wanted her “Frozen” character to be the “opposite” of a traditional Disney princess.

“I want him to wake up with a smile on his face. I want to blow his nose. I want her to talk too much and too fast and wear her heart on her heart and trip over things,” she said. “Real irony for a girl who's lovable but not put together, and thankfully the whole experience was really collaborative. In between some things they wrote, and others they didn't, and they kind of let me take the reigns.”

Both “Frozen” movies have grossed more than a billion dollars at the worldwide box office. The franchise stars Idina Menzel as Elsa, Jonathan Groff as Kristoff, and Josh Gad as Olaf.

“Frozen 3” will be released in 2027, although the cast has not been confirmed to return.

“I guess if we all stay… what are we waiting for?” Bell said on “The Tonight Show Starring Jimmy Fallon” in 2022.
