Will Smith goes on stage at the Oscars and hits Chris Rock then verbally threatens him from his seat

only you can answer why you care.
I don't care about celebrities I just find it bizarre that people get so wrapped up the lives of these vacuous ego maniacs. I can see being a fan of a famous personality but this hero worship stupidity baffles me. They know every detail about their chosen object of their devotion and talk about them as if they a member of their family.
What's up with that?
