No, these are only Fan Clubs created Von fans. We share photos, videos, links, opinion, etc. but there aren't any Berühmtheiten here. For example, this Fan club (Andrew Lincoln) was created Von a Fanpop user for us all to be able to talk about him on this website, but he's not on this website.
If Du want to contact him, you'll probably find him on twitter or/and facebook. Du can also write him a letter and send it to his Fan mail (google it)!
