Is there a way to talk to/meet a celebrity over the internet?

Ok so I'm 12 (almost 13) and I have recently developed a crush on a celebrity my age, and I really want to meet him. The problem is that there is no way I can go to Hollywood or where ever he is (I live in Oklahoma) because of my parents. I know there is Twitter and Tumblr and all of that, but I'm sure a thousand other people are trying that, so my question is: is there a way to talk to/meet a celebrity over the internet? If someone knows can you please tell me?
