DRAMA ON THE HILLS?

PageSix posted this interesting item today:

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."

But we have to wonder how it could be true anyways... After all Audrina lives in a separate guest house on the grounds of Lauren's new home. So her bedroom is not even in Laurens house!

Could this have come from Camp Speidi?
