Attention seeker
This is an exceptionally charitable way to put it.
I am politically silenced from stating bluntly exactly what this is, which is why this individual is able to play this game with a very, very, very thin illusion of being a bit of an odd innocent with a massive lack of self awareness, and have people make excuses for them. And this kind of behaviour generally escalates until it encounters a significant boundary.
Russell Brand has benefitted from similar generosity and indulgence. I think we've all got a bit too #kind for common sense now.
