MTV Movie Awards: Halsey Performs "Castle"

'The Huntsman: Winter's War' co-stars Chris Hemsworth and Jessica Chastain introduced the singer to the stage.

Halsey performed her single "Castle," off of her debut album, Badlands, at the MTV Movie Awards.

The singer was accompanied by an orchestra as she performed in a revealing white bodysuit on the outside stage at the Warner Bros. lot in Burbank. Snowflakes fell onto the stage and swirled into the audience during her performance.

"Castle" also appears on the soundtrack for The Huntsman: Winter's War, starring Charlize Theron, Emily Blunt, Chris Hemsworth and Jessica Chastain. The pic is set to bow April 22.

Hemsworth and Chastain made a special appearance at the awards show to introduce Halsey's performance.

The MTV Movie Awards, hosted by Kevin Hart and Dwayne Johnson, were taped Saturday night and aired Sunday on MTV.
