We've mentioned her name already, and she was always inevitably going to make an appearance herself. The Queen of Pop, Madonna, has been going by that name for way over half of her life now, so it might as well be her real name. Given her global profile, you'd expect that everyone would know what her real name actually was, but surprisingly few do. Can you guess? If not, it's.... Madonna.
That's right, it's her real name. Everyone assumes it's a pseudonym, but she was born Madonna Louise Ciccone on August 16th, 1958. The name does of course have religious connotations, and that's because she's from a strict Catholic family. Her mother, who passed away when she was less than ten years old, was also called Madonna. It would be an incredibly pretentious name to choose for yourself - which isn't entirely out of the question for Madge - but in this case, she didn't.
