Thanks to Kristen Bell [1], one Frozen fan became an honorary Princess of Arendelle.

As if we couldn't adore her any more, the actress took it upon herself to leave a message in the voice of her Frozen character, Anna, for a 6-year-old girl named Avery Huffman who was diagnosed with an inoperable brain tumor, according to her official CaringBridge page [2].

Bell even took a moment to quietly confer with Queen Elsa, who said Avery was '"such a good girl and that you've been so brave." Before she signed off with a "I've got to go build a snowman with my friend Olaf now," she gave a few shout-outs to Avery's family and friends.

Avery's dad, Brandon — who has chronicled his daughter's struggles on Twitter with the #AveryStrong hashtag — posted the full video of the voicemail along with her stunned reaction. Princess Avery — it's got a nice ring to it, doesn't it?
