I'm not sure what this video is for. I assume it's a music video, although it might be a commercial or something. It could be for the song "Robot" since Miley was doing the robot dance on set (see 2nd pic). If anyone knows what song the video is for please post a comment!
UPDATE: The video is apparently for Rock Mafia's new song called "BIG BIG BANG."
A few more pics from the set at Mileyweb.org.
