Justin Bieber for spitting on his fans over his hotel window in Brazil to impress his friends. Those little girls were waiting all day long for just a chance to see him. He didn’t even bother apologizing
I always liked Justin Bieber when I was a teenager (whilst on the outside I pretended to hate him to be like the cool kids) but I don't respect him much nowadays after seeing the way he treats some of his fans at events and signings and stuff. He seems very obnoxious. I try to understand and empathise that he's dealt with life in the public spotlight for pretty much his whole life, but at the same time, it's not hard to have some common decency as a human being in my view, which sometimes he seems to severely lack.
I think it is easy to say this: Mike Tyson. After rigging the fight with Paul, I realized he has 0 respect for his fans and only cares about money. He actually said he doesn't care about his legacy. Maybe he doesn't, but his fans do respect his achievements..
I don't respect or lack-respect for celebrities, to me they are almost like imaginary beings who's purpose is to entertain me via whatever device I am watching/listening to them from.
