Which celebrities are the nicest?

That's it. People will question whether Johnny Depp is nicer than John Travolta. Or, "Is Selena Gomez or Mila Kunis nicer". I say neither. They're the same in most cases. It depends on who you ask, of course. And it also depends on how much media each person receives! I wanted to answer one of these question on Yahoo answers and, unfortunately, I got disliked because the stupid people of Y! are deprived of their dislike privilege on FB. So yeah. That's how it goes. Who do you vote for as the most popular celebrity?
