There's a video of him playing with himself whilst looking at a female fan in the crowd from years ago.....
He seems to have a problem with excess perspiration and has developed a habit of checking his smelly levels by sniffing his fingers. Sad thing is that he must be aware by now that the media are watching him pretend he is not doing it, when we all know he is! I feel quite sorry for him in some ways, but in others l just think he is a gross weirdo.
