I certainly wouldn't want them to show up. And it has nothing to do with them personally. For some reason, it just irritates me when super famous people show up at one of the concerts with their entourage and turn it into a publicity thing for themselves. It's like, "Oh hey look at me, I'm at the U2 concert!"
Like Paris Hilton was supposedly at the Rose Bowl show (not that I'm in any way comparing her to the Royal Family. I am not)...do you honestly think she understands what any of the songs are about? Probably not.
It's a rock concert, for fucks sake. Not your publicity stunt.

Sorry if that was an incredibly bitchy thing to say.
