Claire Crosby sure has a lot of fans for a four year old. Alongside her father Dave, the Crosby's have grown quite a following posting adorable covers on their YouTube channel. Naturally, among the numerous song the duo have performed, there have been several Disney tunes, including "I See the Light" from Tangled. This, in turn, has built them a realtionship with Disney, who invited them to create a video for "A Whole New World" at Walt Disney World and, most recently, brought them to the Walt Disney Animation Studios in Burbank to sing "When We're Together" from "Olaf's Frozen Adventure." Take a look:

Pretty cute, right? By the way, if you missed "Olaf's Frozen Adventure" playing before Coco in theatres or airing on ABC last week, you can now download the film on Amazon along with bonus shorts (which Alex recently reviewed). Happy holidays!
