Wow, we never thought these Hills stars would be willing to put their differences aside for a cover shoot with Rolling Stone. Well, come to think of it, we know Heidi would do just about anything for photo-op, but we figured Princess Lauren would put up a fuss and get her way. Though the two agreed, the magazine is reporting neither spoke for the entire nine hour shoot. Now if we were the art director on that shoot, we definitely would have gone for the money shot with the frenemies holding hands - just cuz we're haters.
