We swear Rihanna just does stuff to cause bare controv the majority of the time, but she's caused a right old stir over a picture she's posted to her Instagram account.
And before any of you boys out there get excited, they're not more topless photos (although you can check more of those out here).
RiRi posted a snap online of herself on a mate's shoulders at Coachella festival, doing stuff with a white powder on the top of his head, along with the caption "Memories don't live like people do #coachella"

Twitter soon went crazy with speculation over what the white powder could be, and RiRi soon tweeted: "I'm crazy, and I don't pretend to be anything else."
However, we think there has to be some reasonable explanation to all of this - perhaps he just has really bad dandruff?
