The getup features a bra top inspired by Hershey's Kisses (complete with Hershey-style labels emerging from the, erm, peaks) and a pair of silver high waisted knickers.
As well as starring in the racy photoshoot, though, the popstar gets a chance to speak about her recent political awakening: "When I was a kid, I asked questions about my faith. Now I'm asking questions about the world."
She even touches on the thorny subject of universal healthcare in the US:
"I think we are largely in desperate need of revolutionary change in the way our mindset is. Our priority is fame, and people's wellness is way low. I say this knowing full well that I'm a part of the problem. I'm playing the game, though I am trying to reroute. Anyway, not to get all politically divulging and introspective, but the fact that America doesn't have free health care drives me f***ing absolutely crazy, and is so wrong."
What do you think of Katy's stance?
