Kristen Stewart was back to work in front of the cameras today on the Wales set of Snow White and the Huntsman. Chris Hemsworth rode horseback alongside Kristen during yesterday's intense, armor-clad scenes, but this time Kristen was alone with her white horse in a softer and more familiar Snow White costume. This isn't the first time Kristen's worked on a beach location. Last Fall, Kristen and Robert Pattinson visited Brazil to shoot the highly anticipated Breaking Dawn: Part 1 honeymoon night swim. Twilight fans will finally see those hot moments on the big screen when the first installment of the series hits theaters Nov. 18.
