Disney's "Frozen" has taken the world by blizzard with its music. Idina Menzel, who plays Elsa in the film, sings "Let it Go" which is on the top 100 Itunes chart and everyone and their grandma seems to be singing it.
But, what is really amazing is Kristen Bell who is the voice behind Anna.
The romantic comedy actress, and now songbird, shows off her pipes in the film without people even knowing its her! The whole cast of Frozen hosted a small gathering where they all preformed the songs that they sang in the film.
Critics call Kristen Bell's preformance shocklingly good. She sings all three versions of Anna, child, pre-teen and teenager live! Although she doesn't actually sing all three versions of Anna in the film it is definently interesting to see her do it infront of a live audience.
