Mate, when I briefly worked for a large PR firm down in Lun-dun in the mid 90s (in the days before celebrity super injunctions) not a single day would go by where we wouldn't be contacted numerous times by the agents of hundreds of A-list celebrities (premier league stars included) whose job it was to keep their "product" clean. The number of stories I personally suppressed (and I was just a junior member of the team and didn't have any dealings with the HUGE stories) and then fabricated "alternative scenarios" for the gutter press to lap up and print in their papers the following day was astronomically large. You wouldn't believe the shit that goes on behind the scenes, it's a very murky world out there. All I'll say is "don't believe everything you read".
Now I obviously don't know for certain if there's any truth in what Karen says (I got out of the "business" as fast as I could due to the stench of it all making me feel sick and because it was just stop-gap employment whilst I searched for a suitable job in my chosen field) but I don't doubt for one second that this sort of crap still goes on to this day. Every time you pick up a paper, read a story, and say to yourself, "That's got to be bullshit!" the chances are, that it is exactly what it is.
