What should you get a ten year old girl for her birthday?

my little sister who is ten years old is here to answer your question:HI. Well not anything like Hannah Montana or Jonas brothers. they don't like that. Lady Gaga is cool. Black eyed peas. Check what kind of gaming systems she likes: DS, Game cube, Wii. also shopping: a shopping spree where she can pick out whatever she likes. or days out, because they like to feel special. not princess special, just special to you. maybe a zoo or bowling or a water park. make sure it is a clean place though, not a cheap place. anything else tell me i answer questions about ten year old girls cause i am one!
