I think most of the people agree that celebrities are living a life that normal people like us are a tottaly distant. They are maybe troubling with paparazzies all the time, they dont have a private life but on the other hand, they are on the cover of the famous magazines, they are getting their clothes from high-fashion designers for mosty free and we are paying them alooot of money, they are attending to high class parties, film premieres, ceremonies, front row fashion shows, award shows... And sometimes people give money for them to wear their clothes, attend to clubs & parties, show off at their restourant etc.
I would be famous for as an actress or as a singer. Because I like both of the subjects and they are interresting. They are earning a lot of money and their jobs are fun and not monotonous. Plus, most of the famous people I love and know are singers and actresses.
