Last night's season finale of The Hills only served to further prove that the best part about the show are the teasers for upcoming episodes.

Oh, but Lo did mention something about cheese being bad for her behind, and I could totally relate to that. But still, who isn't psyched for season four, after seeing that preview? Clip above, and after the jump, the rapid aging of the dog with two mommies.

That dog sure got big since last week:
