Katy perryGold lorry enthu­si­ast Katy Perry's popped another teaser for her new single online and this time it actually features a bit of said single.

The clip features a white cat in a posh living room eating some feathers before roaring at the camera. A clip of what we assume is 'Roar' can be heard but really it's just some "woah woah woahs".

The song's out on Monday so we'll know more then.
