How to act around a popular girl?

[Lila]

I'm hanging out with a very popular girl soon, how do I act? I'm scared she will not like me after it? We are close on facebook but i'm scared I'll lose her if I act the wrong way. I will be myself, I just want to know what kind of things to say and talk about?

Mimic her every move, it is the sincerest form of flattery

Talk to her like you talk to her on fb. Talk about something that everyone has something to say like movies BUT dont talk about the weather! And if ur urself and she doesen't appreciate you, then her lost

Trust me she is just another person, and she might also be a little bit worried about you liking her. Plus just be yourself because it would suck if she didn't like you because you were being fake. Don't try to impress her or everytime you guys hang out, you will be miserable trying to impress her.
Talk about the same things you guys chat about on facebook, talk about a movie you have recently watched, talk about something cool you did
Be confident!
Make sure you are dress comfortably and good
Have good hygiene
be polite

You act like yourself.

just be yourself, treat her the same way you treat your other friends and if she doesnt like something your doing then just drop her
