"I was really unsure about her being Belle because I've never heard her sing. I take it all back. Chills all over the place," wrote one fan.

On top of Emma Watson singing, Disney have also released two new TV spots which feature even more new scenes – including your first look at Belle and the Beasts iconic snowball fight.
The film, which isn’t due for release until March 17, 2017, also stars Dan Stevens as the Beast, Ewan McGregor as Lumiere, Ian McKellen as Cogsworth, and Emma Thompson as Mrs. Potts.
