Each person has the right to have a private life. A persons being famous does not change the situation, because famous people are like us and do not want their families in too much danger because of the Paparazzi. Besides, the private life of famous people does not interfere with their work.
Firstly, famous people are usually in front of the eyes of the public. Their life story can be easily reached via internet, magazines, etc. However, the media search not only their life story but also their private issues like their family, friends and money. At this point, famous people usually become angry with media, because they do not want their families or friends to be in danger because of the media. When their relatives are known, some people can follow up and disturb them. Therefore, famous people usually do not want their private life to be known by public as being right.
I believe that the great attention to the private lives of famous people is not very good for public in general and for me in particular. 
As a result, we can say that famous people have the right to have a private life. They do not want their private life to be in front of the eyes of the people as being in the right. Moreover, the thing which interests us is their work not their private life.
