Wow! Two episodes of The Hills, back-to-back, on one Monday night. You can only imagine the drama that went down when Lauren Conrad learned that the one and only Stephanie Pratt - sister of Spencer Pratt - was in her class at FIDM!

Elsewhere, Whitney Port bid farewell to Teen Vogue and got a cool new job, where she works more on the styling end of fashion. Clueless Spencer and plastic Heidi Montag, meanwhile, continued their epic feud / mini-breakup.

That's just the beginning of an hour of excellent reality TV, fans. Click on our full episode guides for the full rundown of last night's action on The Hills ...
