Sloppy seconds

Ummm excuse me but what are The Hills girls doing crashing the Hawaiian vacation of Brody and buddies? Could these girls please get a life, a job, something. All of a sudden there is a mutual attraction between Brody and Audrina that has always been there? When did this come about, before or after Lauren was smooching his face off? Seriously, how awkward is it to tell your friend who has dated Brody that you just spent the night in his room? Lauren has to be PO'd... Who needs enemies!
