It's all part of the media machine. For some reason, many humans feel that for the justification of their petty toils, they have to turn to the lives of the rich and famous, and as a result, TV shows, magazines, and many other media outlets make ridiculous amounts of money for that reason. And the more sensational the break-up or scandal, the more money they make by sucking people into the real-life soap opera. If there aren't any real scandals occuring (and we all know there usually are quite a few, due to the clashing egotistical celebrities) the media will invent some for their cash cow.

My answer? Ignore it all. Don't let yourself be pulled into the sham.
