Audrina and LC don't get along?

Things between "The Hills" stars Lauren Conrad and Audrina Patridge may not be as chummy as they look on the screen. We hear that Patridge, who is roomies with Conrad, locks the door to her bedroom when she leaves their LA apartment because "she doesn't trust Lauren," according to one source. Not to mention that Patridge "gets really annoyed at Lauren's cats because they pee on her rug and on her bed." A rep for Patridge said, "This is ridiculous. Audrina loves living with Lauren."

I have to call bs - Audrina lives in the guesthouse so of course she would lock the door if she went out. And if this is about the old apartment days, If I had a roomie I would lock the door to my room too if i wasn't there. Not necessarily because of the roommate but say they had a group of people over, you cant watch a few people every second, something could get stolen.
