Original presents for a girl?

Okay, I had no idea what to title this question, it’s kinda hard. So theres this friend of mine, that I’m kinda good with, not that good, but she thinks we’re like BFF. She’s turning 15 and I’m already 17. So she’s much younger then me. She is a really nice girl though, so I want to give her something original for her birthday, because last year I totally forgot her birthday. But I don’t know where to start! Could you guys help me? Don’t worry, NOTHING is wrong, because I don’t know her that good anyway. But here are some things that she likes:

-she LOVES the Jonas Brothers!! -she likes flower-printed shirts?! -loves make-up but isn’t allowed to wear it that much. -She loves reading chicklits. -She’s a total drama-geek!! She goes to the same theatreschool as me and she’s planning on being an actress. Right now she’s actually directing a childs-play.

Thats all I know :( You see why its so hard picking a present for her? Can anyone help me? She gave me something really original and special for my last birthday so I do want something cool for her. Please don’t think of me as a bad friend:(
