Effects of celebrity media coverage on celebrities

On an individual level, it's very interesting to me the range of responses people have to becoming media celebrities.  On one side of the dimension, there are celebrities (Paris Hilton) who court media attention and in fact who creatures of the media.  They wouldn't exist without continuous media exposure.  On the far other side, there are those celebrities who manage to maintain privacy and stay out of the limelight (the late Paul Newman comes to mind).  In the middle, are the majority of celebrities, achieved or created, who are ambivalent about media exposure, sometimes welcoming it and sometimes feeling angry, annoyed, disturbed about their privacy.  There's also the category of people who don't seem to be able to handle celebrity and what comes with it.  It puts me in mind of VH1's series,  "Behind the Music".  The narrative is almost always the same.  A young person gets famous quickly, can't handle it, falls into drugs and general overindulgence, is in danger of losing their career, but gets their act together (rehab, therapy, etc.) and at the end is back into their career.  The formula is a rapid rise, a quick fall, rehabilitation and finally redemption.  Then there's the group of celebrities who strike back at the media.  Maybe they sue in court for libel or defamation of character or perhaps they physically assault the paparazzi.  Of course, if they do that, it plays into the hands of the paparazzi who get paid bigger bucks for pictures of celebrities who assault the paparazzi.  In short, how do celebrities adapt to the celebrity ecosystem?
