The Millers were never considered "American Royalty". That title is held pretty much for the members of the Kennedy family and that's it. Actually, most Americans don't even know who the Millers are, even now, after all their glossed-over high profile marriages and divorces. As someone once pointed out on another site, the Millers were really only "visitors" to the US, the daughters having been primarily brought up in Japan and then European boarding schools. Mr. Miller has been an avid anglophile for decades and I believe is now a British citizen. The mother, as we all know, is from South America. Part of the reasoning behind the girls move to England was that they weren't getting enough PR over here in the states, what with the Hilton Sisters pretty much coveting the "celebutante" roles for now. In Britain, mainly because of MC's connection by her marriage to the European royal houses, they are, in effect, treated more like "royalty." Though there's still not much PR for them unless MC is seen at some gala event. There's nothing new on them at all, and I'm sure it's not their idea. And I pretty much believe it's because, not only doesn't the average person know who they are but I don't think too many people care.
