How do you wrote to celebrities on Twitter?

[give_em_hell_kid]

Okay, I'm useless on Twitter, it's so confusing. :L
So, I would like to know how to write to a celebrity you follow?
Is it likely that they will reply?
What sort of things are you supposed to write? s: I don't want to sound like a psycho stalker loser fan?
Thank you for any help you can give, especially the last bit. (: Have you ever wrote to a celeb?

search for the one you like. follow them and then tweet them but using their name thing on the page with the @

[EMILYY.]

go on write a message and if you follow them, put @ and their twitter username should come up, and then just write a message.
to be honest, it's highly likely they won't reply as they get thousands of people who try and write to them every day. write anything you want xx
