Jay Z, who says he's not a member of the Illuminati.
Vox has published an article on "9 questions about the Illuminati you were too afraid to ask." It apparently ran some time ago, but I missed it, and not being an expert on the Illuminati, it told me some things I didn't know.
One of the questions was, "Are Jay Z, Kanye West and other celebrities in the Illuminati?" and the article by Phil Edwards has this sentence, which I enjoyed: "We contacted Kanye West and Jay Z's spokesmen, but they did not return our request for comment." Yeah, I'm amazed they didn't get right back to him. Edwards notes that on previous occasions, they have both denied being members.
