Eh, I can't say I really hate any of them. The thing with celebrities is that they will do one outlandish thing and the media is all over them like white on rice, and the majority of time the stories are so exaggerated that we can't be sure of what is true or what is not.

BUT, if I had to choose one I don't really care for it would probably be Lindsay Lohan, only because more than a few times I have seen her in action without the media having to embellish her antics, and she was not too friendly.
