What's a Princess?

To me this should be a pretty easy definition. However, I was just watching the new show on CNBC called Princess. It seems to be just like "'Til Debt Do Us Part" but it's about just one person who considers herself a princess and she has a lot of financial problems because of it. So they stopped people on the street and asked them what a princess was. Not one person said it was a member of the royal family. Instead, everyone described it as a spoiled brat who needs to grow up who is high maintenance. I think sure it's great to look good or go after diet pills that work. However, I think princess has always been one of my favorite words let's not spoil it; literally.
