Katy Perry is usually a trendsetter, but now she's the latest to join a movement: planking!

Planking, i.e. the act of laying down and taking a photograph of yourself, is sweeping the Internet as people try to come up with crazier ways of accomplishing the feat -- planking on top of two camels, planking on top of a fridge, etc.

But Katy planked a boat, and she liked it! The singer Tweeted this fun pic of herself doing some relaxing planking.
