Then again on 15 January 2014, she posted that they were getting ready for the video shoot. Natalie has posted a first impressions teaser of the video, and the video premiered on 27 March 2014.

The video starts off with Natalie singing to the screen in numerous positions mainly using lots of hand gestures. The scene eventually goes with Natalie inside a box like small area where she swings around slowing whilst singing the song. During the chorus, Horler is pulling off her famous moves and hand gestures whilst over dancers break-dance behind a futuristic wall reminiscent to the Pyromania video. Throughout the song, Horler is seen to be lying on the ground, in the box area, in the futuristic area dancing with other dancers whilst singing.
