The world now has one more princess, thanks to Kristen Bell. The warmhearted actress used her star power to make one young girl’s dreams come true.

Bell transformed into her character, Princess Anna, from the animated film Frozen to leave a voicemail for 7-year-old Avery Huffman, who was diagnosed with DIPG/brain cancer, according to her foundation’s Twitter page.

“I hope you’re having a great day and playing a lot with Hoppy Jumpy,” Bell told Avery. “Avery, my sister Elsa says she’s heard that you have been such a good girl, and that you’ve been so brave, she has decided to crown you as an honorary princess of Arendelle! Wow, that’s so exciting! I think you’ll make a great princess,” she said.

“I’ve got to go build a snowman with my friend Olaf now,” Bell told her before sending shout-outs to her loved ones.

Avery couldn’t be more excited to hear from Princess Anna, smiling and bouncing with excitement.
