In the season 4 premiere of The Hills, Audrina and Lo finally put their long-simmering tension on the table. While Lo insisted she'd been unfairly blamed "for the reason you and Lauren are drifting apart," a cool Audrina told her, "I have friends that treat me good and I feel included, and you don't do that. But I just don't care. We'll never be friends." There's always next season to bond!
