What should I get my friend for her 12th b-day?

Her birthday is TODAY! ahhh i dont know what to get her. im going to wal-mart. she isnt actually my friend...she isnt really anybodys but i got invited so ummm she likes justin bieber but someone already got her some jb stuff (the gurl that did told me) so i dont want to risk buying the same thing. she does want this minute to win it board game but my mom says we prob wont see it at wal-mart! i dont want to get her a gift card cuz thats being well...lazy and cheap! I NEED HELP?! what is something that all 12 year olds like?
