Madonna (nickname)

So, you know how some people have special names that their friends and family call them? Well, Madonna is a famous singer who also has a special name that people call her. Her real name is Madonna Louise Ciccone, but her friends and fans call her "Madonna." It's like a nickname that she's had since she was young, and now everyone knows her by that name. It's kind of like if your name was Susie, but your friends called you "Sooz." Does that make sense?
