MTV's last remaining cash cow and its boring spinoff both returned to the air with new episodes on their new night Tuesday. Follow the links below for recaps of both The Hills and The City!

• On The Hills, Lauren Conrad is a thing of the past and Kristin Cavallari (pictured) is the new star. And boy, was she shaking things up from the get-go in "It's On, Bitch!" Sure, it's all fake, but it's entertaining! Check out The Hills recap here.

• Three thousand miles away on The City, Whitney Port's spinoff has been made over into a "workplace drama." As opposed to the riveting "relationship drama" of last season. The verdict on version 2.0? Check out The City recap here.
