Thereof, can Kristen Bell actually sing?
She is voiced by Kristen Bell as an adult. At the beginning of the film, Livvy Stubenrauch and Katie Lopez provide her speaking and singing voice as a young child, respectively. Agatha Lee Monn portrayed her as a nine-year-old (singing).
Just so, did Kristen Bell really sing in frozen?
Bell reprises her vocal performance as Anna in the upcoming sequel opposite Idina Menzel. The voice of Anna naturally sang a few bars from Frozen and Frozen 2, performing “Do You Want to Build a Snowman?”, “Into the Unknown” and “Let It Go” with Fallon, but it was the Disney repertoire depth that really impressed.
