Whether she's live tweeting her UberPool experience or crying over sloths, Kristen Bell always manages to make our day.
Except this time, she's really done it, and unforgettably made the day of one very special Frozen fan!
Last month, the actress left a voicemail for Avery Huffman – a six-year old diagnosed with diffuse intrinsic pontine glioma, an inoperable and cancerous tumor — in the voice of Princess Anna!

What's better than that??
Oh well, just the fact that Kristen, ahem Princess Anna, dubbed Avery the "honorary Princess of Arendalle!"
Brandon Huffman, Avery's dad, even caught the whole thing on camera just to see his daughter's sweet reaction to hearing Kristen's sweet voice, which is only now going viral!
Catch the video (below), but prepare to be get chills from the magic!
