He's been around the world of music and general superstardom for so long that you might occasionally forget that Jon Bon Jovi doesn't really sound like the kind of name a real person might have. It isn't, though, it's a stage name, and one that's quite obvious when you take the time to notice it. The 'Livin' on a Prayer' singer and rock star actually stayed closer to home when choosing his name than you might have guessed, though.
His real name is John Francis Bongiovi, Jr. He never truly intended to change it, either, but got bored of having to explain to people how to pronounce it before the band were introduced, or when trying to obtain a record deal. He would tell people he was called 'Jon-Bon-Jovi', which was supposed to help them pronounce his second name, but in the end, it was just easier to go with the phonetic spelling.
