Though it pains us to say this, we think we may be over Lo Bosworth, the incipient villainess of The Hills' fourth season. When we first met Lo, she was amongst the most breezy members of Hills forerunner Laguna Beach , but there's no place for cute quips on The Hills when out-and-out bitchery will win the day.

Lo, you're on notice: we're officially frienemies now. [MTV ]
