The pseudo-improvised reality series The Hills, as it plays out beyond MTV on tabloid covers, is back stronger than ever after a three-month hiatus. Last Monday's return averaged 4.8 million total viewers, a new high for the show. The Hills, set among young aspirants of the Hollywood Hills music and fashion industries, continues to track the emotional warfare between former best friends Lauren Conrad and Heidi Montag while delving more deeply into the twistedness, gaslighting and superficiality of the boyfriends who ensure that the tortured rivals treat each other like Crips and Bloods. Yes, it's the guiltiest of guilty pleasures (10 p.m.-11 p.m., MTV).
