Katy Perry: Everyone wants to be on Madonna's d*ck....... She said about Madonna... "You really have to prove that you're an authentic person, and you can be trusted, to be in a circle of friends with her. Which I totally understand. You have to really guard your heart when you're on this kind of level. You can't have weirdos around...because everyone wants to be on your dick." #katyperry #rollingstones #madonna by madonna_art
