Fun sleepover ideas for preteen girls... please answer!!?

Hi I am planning on inviting a couple of my friends over for a sleepover tonight. What are some cool movies (rated no higher than PG-13 please), yummy snacks, games, and other things we can do? We all like playing with make-up too (: i also have some video game systems, and i have rock band, and many others. My dog might be a bit of a problem because he is just a young pup, and can't stand not having attention. We are all really close and talkative, so we will play games like truth or dare, and would you rather, but those games get old, so some new game ideas too please =] we are all huge twilight fans =] I was thinking we could have a "fashion show" but close isn't that fab. thank you for your ideas =]
