Makes me wonder what Jean Paul's real name is... I mean c'mon! And if anyone believes "Lou Schuler" is his real name I don't know what to say
David Bowie's real name is Dave Jones but he changed it because people confused him with that guy from the Monkeys. So unless your name is Pavel Tsatsouline or Arnold Schwartzeneggar, or you want to move to L.A. and star in a reality show then I'd say don't worry about it.
