Well that's the problem with these celeb-realities. We in essence created a monster, and the monster eats its victims.
These reality tv stars don't know how to handle the pressure, the light, because they're doing it to seek the fame.
For example, do you ever hear about Johnny Depp, Robert Redford, Daniel Craig etc? Yeah, when they have a movie out, but every day? Not really.
I think there's
seekers (only way they stay relevant be in the tabloids) (Britney, Paris, Lindsay, *insert reality tv star of the week*)
people who don't promote themselves every week, these are usually the 'class acts' (Kate Winslet, Liam Neeson etc)
and then there's the people who disappear off the radar completely and then come back every 4yrs (Daniel Day Lewis) haha
