No, these are only ファン クラブ created によって fans. We share photos, videos, links, opinion, etc. but there aren't any セレブ here. For example, this ファン club (Andrew Lincoln) was created によって a ファンポップ user for us all to be able to talk about him on this website, but he's not on this website.
If あなた want to contact him, you'll probably find him on twitter or/and facebook. あなた can also write him a letter and send it to his ファン mail (google it)!
