Hate to beat a dead horse on an old topic, but I think it's safe to say she won't do such a thing. You can rule out the leaked nude selfie, because Katy damn sure knows the consequences of that (Just ask Rihanna...) Second, a nude photo shoot...not happening with all the teenagers and young kids she draws one song after another..
It's all just a dream for now, especially for guys who have the mentality and the hormones to imagine it.
But if you think you can pull off a miracle, be Katy's next lover and sleep with her, do it!! If you succeed, just don't talk about it for the rest of your life though
