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