After complaining of a stomachache, 7-year-old Kamryn Slater was diagnosed with kidney cancer this past April. Her treatments in the hospital are rigorous, but one recent visit featured a most pleasant discovery: Her nurse, Tom Shelley, is a big fan of the Disney movie "Frozen," just like Kamryn.

Naturally, the epiphany resulted in an impromptu duet of one of the movie's ultra-popular songs, "Love Is an Open Door." Kamryn's mom, Andrea, posted their performance to Facebook, and it's been shared over 230,000 times.
