WATCH: Katy Perry Debuts Video For 'Hey Hey Hey'

Katy Perry goes back in time and really slays in the brand new video for her track “Hey Hey Hey.”

“After a year of peaks and valleys (remember, it’s all a journey), I wanted to end 2017 with a fun, triumphant piece of pop candy,” Perry wrote on Instagram.

“Just think of it as a glam little stocking stuffer from me to you.”

The pop star explained that “Hey Hey Hey” is one of her favourite songs on Witness. “It embodies the fighting spirit I always want you to be able to find within yourself, and to see in me,” she said.
