No, it is not important to show off the personal issues of a famous person, because a famous person has private issues just like everyone else. A famous person might have medical issues, or family issues, and they need their space. The public should be respectful of this and allow them to live their private lives.
Most people do not care about the personal lives of famous people. Also, it is an invasion of privacy to publish details of a person's private life, even if they are famous. Tabloids should not pander to the public with outrageous stories about scandals involving celebrities. It is rude and shows poor taste.
