How can I get in touch with Emma Watson?

I am a huge fan of emma watson and love everything that she does. She is just so perfect. I am wondering if there is a way that I can get in touch with her. I know it sounds like I am just another fan, which technically I am, but I want to get to know her as a friend as well. I know its hard to get in touch with celebrities but I might as well try. Can anyone help?
