My friend wants to get a haircut like Justin Bieber's, trouble is..?

her hair looks like this: http://cdn.blogs.sheknows.com/celebsalon.sheknows.com//2009/09/taylor-momsen-long-hairstyle-sept-09-693x1024.jpg (except its shoulder length and no sidebangs or layers) how should it be styled and cut to have the "Justin Bieber" look?
