The majority are interested in reading about celebrities. However, all the people are different: the ones would like to be popular everywhere, but the others are more reserved and insular.
In fact, many famous people like being discussed all over the world. They think that due to scandals they will be able to get fame, live in the lap of luxury and have a lot of money. Anyway, that is their point of view.
On the other hand, not everybody prefers to reveal the secrets of the private life. For such kind of people it is important not to bring out family scenes and problems, as they do not want them to be disputed in public. But in spite of this, sometimes journalists can be too insistant, trying to get at as much information as possible.
To sum up, material about stars should be published if they approve of it putting the signiture. As it seems to me, that would be fairly by celebrities.
