@FF I know, I would do the same thing, Just pretend I didn't know who he was, and talk normal. I'm also shy, I wouldn't want to be in the same room as them even if it was for free. I would feel weird. But if I met them in a bar or at the supermarket or something like that it would be more natural, and therefore more ok I guess. But I still wouldn't mention that I knew who they were. XD
