'Frozen 2' Release Date & Cast News Update: Kristen Bell Calls Sick Little Girl as Princess Anna

The Kingdom of Arendelle has a new Princess and her name is Avery - Princess Avery Huffman.

In a heartwarming and tear-jerking moment, actress Kristen Bell, who voices Anna in the hit-movie "Frozen" got into full character and took a moment to send an uplifting message to six-year-old Avery, who is stricken with an inoperable brain tumor.

In the Caring Bridge page dedicated to Avery, it was narrated that she was diagnosed last June 30 with DIPG or Diffuse Intrinsic Pontine Glioma, a cancerous brain tumor that is inoperable. This type of brain tumor is found in the pons, a part of the brainstem located on the lower back of the brain, near the top of the spinal cord.

Like any other young girl, Avery is big fan of "Frozen" and so imagine how she felt when she heard the voice of Princess Anna directly addressing her and presenting her sweet praises. The moment gave the little Princess a reason to smile.

Kristen Bell aka Princess Anna sent a voicemail to Avery to say "hello." She also delivered a message from Queen Elsa, declaring Avery as an Honorary Princess of Arendelle, praising her for being a good and brave girl.

Princess Anna, however, needs to go and build a snowman with his friend Olaf. Nonetheless, Princess Avery's reaction upon hearing Princess Anna's voice and becoming a real Princess is precious and more valuable than any other treasure.

A video of Avery hearing Princess Anna's message for the first time was recorded by his father. The video has quickly gone viral and garnered over half a million views.

"Seeing her face light up, though, with the message from Anna and the introduction of Buttercup to the home, made up for it. Even in tough moments, Avery finds a way to be strong. In those same tough moments, we struggle to stay strong, realizing just how hard this is for her and for us, but mostly for her," wrote Brandon Huffman in their Caring Bridge blog. "But then when we see her bounce back and get back at it, it gets us back up."

The Frozen sequel, "Frozen 2", is currently in the works with a target release date of 2018. Many are hoping the Princess Avery can take a visit in Arendelle and see her Princess Anna and Queen Elsa. Who knows, maybe she can also build a snowman with Olaf.
