"There are little things you have to forgo (as a celebrity). If you walk around in sweatpants and don't shave or shower, or look a bit sleepy, there's a high probability that there are going to be rumours out there that you're on drugs or starting some sort of spiral downhill. So I've always tried to look my best, and look clean when I go outside. I think I owe it to everybody to show up well-groomed and put in a little effort. It's the least I can do."
Emphasis mine.
Zef: We know that's a lie. Does it hurt when your pants are on fire like that?
