anyone who is anybody

All the most famous or important people in society. Usually used to indicate something as being glamorous, trendy, or chic, which all such famous people have, do, or are attending. I hear that the gala in New York City is going to be a star-studded event. Anyone who is anybody will be there! Anyone who is anybody in Hollywood will be at the movie premiere tonight. It's a very exclusive club, so it's not for ordinary people like us. But I'm sure it will attract anyone who is anybody.
