Pseudo-celeb sighting!

I spotted Spencer Pratt, the ultimate celebrity wanna-be, at the Apple Store at the Grove today.... It really made me think, as this is a class about stars, that there is an absolute difference between stars and celebrities. These days, there are so many people who are famous for no reason other than who they are: Spencer Pratt, Heidi Montag, Paris Hilton, Nicole Richie, Tila Tequila, the list goes on.... Celebrity seems to be more of-the-moment, something catchy but fleeting, where as stardom is something of more significance. To be a star, I think more substance is required, and yet a celebrity can also be a "social phenomenon" -- perhaps, representing the baser values of society. Like now, our generation will be remembered for its reality television, and celebrities like Pratt are the face of this social phenomenon, but can we consider them stars because of that? What do you think? A lot of deep thinking over such an empty celeb sighting...
