Not quite sure what you're asking but I do believe most of the "famous" people live on their own (if they're of legal age that is)
Is there anybody that is. Famous. And they live on there own
i live in the town Harriet Quimby lived in, first woman to get a pilot's license.
Your question is to the point.
But whoever reaches an appropriate age to handle a life on their own, they will live on their own. Which is a personal decision.
However, this has nothing much to do with being famous or not.
There's so many famous people that live on their own, It will take forever to make a list!
