We know The Hills isn't completely true, but could this week's season finale of the show - in which Lauren and Audrina's friendship starts to unravel - be more "real" than expected?

In the pictures above (and the vid below) Lauren Conrad shoots an episode of The Hills with Whitney... and Audrina is nowhere to be found. On Tuesday night, Lauren went out with her sister... and not Audrina. And last night, she was out with her BFF Lo... and again, not Audrina.

Here's Lauren with Lo - whom she's known since her Laguna Beach days - leaving Crown Bar last night.

Does this mean Lauren's friendship with Audrina is over for good?
