Katy Perry has posted a teaser clip for her new music video online.
Swapping cream-firing breast apparatus for actual bullet-firing guns, the 'Part Of Me' video sees Katy going to battle in an all-lady army.
From what we can tell there's a night vision scene, an underwater struggle and a bit where a cropped-haired Perry has a bit of a rough and tumble with a fellow soldier.
The full clip will be deployed on March 21 but you can watch the trailer here now.
