Angelina Jolie's birth name: Angelina Jolie Voight (Ironically, I cannot find angelinajolie.com. Searching for "Angelina Jolie official site" pulls up this: http://www.team-jolie.com/)

http://en.m.wikipedia.org/wiki/Angelina_Jolie

Other famous people who had a "stage name":

  John Cougar Mellencamp
  John Wayne
  Julie Numar
  

And countless others. I sometimes think about getting MyfirstnameMymiddlename.com (but then I think that's stupid, so I don't). But I figure if I buy MyfirstnameMyexhusbandslastname.com, I will suddenly remarry.
