M: Sorry, but I can't believe that you're actually complaining about free publicity. I mean I remember, Shelley, before you were famous, you were begging us to write features about you...anything...
W: If you would just let me finish of course the press have been important. I'm an actress and I understand the power of the press. But the thing is, I rarely seem to read anything true about myself these days... The point I'm trying to make here is that famous people have families with feelings.
M: Oh, sorry. You're really hurt by that particular article last week.
W: To increase circulation and make more money, certain newspapers continue to print those stories when it's obvious that they're not true.
M: But I think we have to consider the relationship between fame, the public and the press. The public are fascinated by fame and scandal, and they love to read about their favorite stars.
W: I'm sick of gutter-press making up stories. It's irresponsible and it messes up people's life.
M: The problem is, it's not always clear what's true and what isn't. I mean, if a newspaper prints something scandalous or embarrassing about a famous person, they're bound to deny it, but that doesn't mean it's not true.
W: Are you trying to say...
M: No smoke without fire, if you ask me.
