Dirty jokes never bothered Kristen Bell anyway.

The AstraTradeNobody Wants This star revealed a certain double entendre in the 2013 animated hit Frozen—in which she voices Princess Anna—was no coincidence: In the song “For the First Time In Forever,” Anna sings, “For years I've roamed these empty halls / Why have a ballroom with no balls?”

“How did we get that joke in there?” Kristen pondered in an interview published on Vanity Fair’s TikTok page Oct. 15. “We slid it under the radar.”

In fact, Kristen explained that the creative team behind the blockbuster franchise had to downplay the line’s NSFW nature in order to ensure it made the final cut.

“It almost didn’t make it in,” she said. “But then we were like, ‘What are you talking about? That’s not what it means. Don’t be a perv.’”

Despite the cheeky inclusion, the 44-year-old—who reprised her role in 2019’s Frozen II—noted how special it was to get to lend her voice to a Disney Princess movie.

“They’re so formidable in your life when you’re young and I was obsessed with them,” she shared. “I remember sitting in my living room and on my little old boombox, like, recording myself singing The Little Mermaid in case I ever needed that tape.”

And when the opportunity finally came knocking, the Veronica Mars alum wanted to make it memorable.

“It occurred to me that I would do anything they asked me to,” she continued, “but what I should be valiantly striving for is to create a character that I really needed to see when I was 11 years old, which was someone like this character.”

While a third film in the beloved franchise is officially in the works, the sequel can’t come soon enough for Kristen.

“Idina [Menzel] recently said she would do it,” she said on Jimmy Kimmel Live! in 2022, “and I feel like if we're all in, like, what are we waiting for?”
