I hate celebrities who are famous without talent. They are just famous because of who they are related to, involved with, or just media attention sluts. The famous for being famous. Socialites without a trade.
I don't hate any, but there are a few I dislike for various reasons: Bieber, Angelina Jolie, Kristin Stewart, Ashton Kutcher, aaand probably the one most people will question...Charlie Sheen. xD
