I definitely seen artist talk about the Illuminati, I think theres a video with Dave Chapelle talking about it. Also Tila Tequila was talking about how they were out to get her for trying to expose them and tell the truth. She ended up having a stint in the hospital, she wrote blogs about it.

Also I read on a forum about Rihanna being part of the MK Ultra Programming.

More like some of the GP are so dumb they actually think it exists.

Like seriously... it doesn't take that much thought to realize that the Illuminati is the stupidest thing ever thought of.
