Given how much some singers pour their personal lives into their music, it's easy to believe that we know everything possible about them. However, sometimes we discover facts about musicians that totally blow our minds.
Perhaps it's something funny – like the fact that Adele's management had to ban her from tweeting after she drunk-tweeted one too many times.
Or maybe you know something about a singer's past – like the fact that Taylor Swift's parents deliberately gave her an androgynous name to give her a leg up in the business world.
Or maybe you know something that seems impossible, but is actually true – like there being three former US presidents with more Grammys than Katy Perry.
