Equestria Girls top dog Ishi Rudell revealed this one over on Twitter. If you like the singing voice of both Rarity and Luna, expect something in a similiar vain with Adiago Dazzle, as Kazumi Evans is providing her vocal talents for the role.
We have a little over a month before the movie official hits theaters. You can get the full listing over here.
Thanks to Andrew for the heads up!
