The Real Names Test

Hi! And welcome to my Real Names Test. This test is scored very straightforwardly, so please don't cheat and look the answers up on the internet. I will be giving a name of a celebrity, pop-star or superhero character (thought I'd widen the scope a bit) and you have to identify their real name (or in the superhero's case, their 'alter-ego' or secret identity if you prefer). There, how hard can it be? You get 1 point for a right answer and nothing for a wrong one or skipped question. Your score will be out of 20 so you'll know how many you got right. Obviously, this quiz is not sex related so everyone has an equal chance. One last word of warning, not everyone in this test uses a different name to their birth name, so for example Lynda Carter (Wonder Woman from the TV), her real name was Linda Carter (and no, she's not in the test).
