I worked for a long time as a missionary and one young man who was getting help (he was a drug addict and for a long time deeply involved in the occult) told me that he attended numerous occult gatherings and often times there was big name celebrities there, doctors, professors etc. He specially mentioned charlie sheen, Ashton Kutcher, and Brittany Murphy (when she was alive) and Charlie's sheen was very high up and always wore a long black cloak.
