The only thing with a fake assassination of someone this young who has been in the limelight for so long, they wouldn't just fade into the darkness never to be seen again (and if they were asked to do that and would not, then they would be taken out, so why not just take them out from the start).

Plenty of stuff is fake. The killer is a good chance fake. Fake murder of a young celebrity who seemed to live for what they do, though, seems incredibly unlikely. (I know, I know, Tupac, lol)
