Is it any of our business?

Over the years celebrities, athletes and anyone else who's under the public’s watch has been abused by the media if they have done something wrong in their personal lives. The question I'm asking is this right? It's been happening for decades and is only getting worse as the media grows. One of the biggest and most recent victims of this is Tiger Woods. Is what he did wrong? Yes. Is it any of our business? I'm not sure, in one sense it is his personal life and what he does off the golf course and away from the media show be kept private, but in another sense he is suppose to be a role model to kids and he is a big public figure, and some people will say that you can't just hide this kind of information from the public if he is going to be a role model and doing all of his commercials.
There have been many different types of cases just like this one. The head coach of the Louisville men’s basketball team has also been caught cheating on his wife, not has a extreme as Tiger Woods but still got caught and was made public by the media. Now he will always have that hanging over him and the whole world knows. Lots of people’s lives have been affected by the media just like this, is it alright for the media to do this just because they are dealing with famous people or is it wrong?
