Katy Perry has unveiled the video for her latest single 'Wide Awake'.

The pop songstress uploaded the video online today (June 19) as the anticipation for her soon to be released 3D film 'Part Of Me' grows.

'Wide Awake' was written for the film and featured on her 'Teenage Dream: The Complete Confection' album.

The video enjoys a sort of gothic fairy tale theme and sees Perry eat a poisoned strawberry.

The clip ends with the singer releasing a butterfly then heading out on stage to perform live.
