Watch a Young Frozen Fan React to a Surprise From Kristen Bell

There’s a new honorary Princess of Arendelle thanks to Kristen Bell.

The actress left an adorable message in the voice of her Frozen character, Anna, for Avery Huffman, a 6-year-old who was recently diagnosed with diffuse intrinsic pontine glioma (DIPG) — an inoperable brain tumor — last month, according to Huffman’s official CaringBridge page.

Bell got into full character for the young fan, congratulating her on being such a “good girl” and “so brave” — and that Anna’s sister (Queen Elsa) would love to make her an honorary princess.

Her parents have been chronicling their daughter’s journey on Twitter with the hashtag #AveryStrong. Huffman’s father, Brandon, posted the full video of his daughter’s reaction to YouTube. See the video above.
