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

Get her concert tickets to the Jonas Bros

Yeah, well, I don't live in the US so that's kinda imposibble
And I don't hvae that much money.

get her something that has the jonas brothers.. perhaps a book with the cover being them, so when she writes in it; she'll think of them AND you.

perhaps little things with the jonas brothers in them,, a shirt, a button, a folder, anything she can use.

I'm a fan of the Jonas Brothers too, so I can give you somethings to get her;
- posters of them, or her favorite jonas brother
- on their merchandise site, they have necklaces, clothes, bags, etc.
( funmail me if you don't know the address! )
- magazines with them in there
