TMZ is a real "news" site for "personality sightings." Since this obviously is news and it is clearly a personality sighting. It is real. Good job TMZ and their contributor.
I have seen a variety of anorexic folk and they all wear long sleeve shirts and long pants, so that is not surprising for someone with a disease related to nutrition shortage. Yes he is wearing his "uniform".
Just bless your lucky stars he is not wearing his shorts, commando, and hanging out as some accounts have reported!
I leave you with that image.
