The more important question is, how many humans are living on earth, disguised as aliens disguised as humans and pretending to be aliens with not-so-human attributes; but what you really should be asking is why are the humans so worried about celebrities and not showing enough concern about aliens pretending to be human on earth.
Well duh every teacher, political leader and every person of importance and all aliens and don’t even get me started with the illuminati families they are all aliens
