[Air-l] celebrity on the web

Greetings to all. I was wondering if anyone knew of any academic work on celebrity homepages or construction of celebrity on the internet? A colleague of mine is interested in doing a paper on this but has had no luck finding any literature on this specific topic. Any leads to degregor@uga would be greatly appreciated (or on the listserv would be fine too). Cheers, Federico de Gregorio
