In this week's episode of The Hills, we witnessed Lauren and Audrina go from frenemies to being best buds again. Stephanie and Spencer continued to feud during a visit to their Nana's house, although we didn't hear any quarreling between Heidi and Spencer, which was a first! This geek didn't discover a whole lot of tech toys, but there was enough tech talk to whip up this week's tech quiz — how well were you paying attention? And don't forget to head on over to CelebStyle to get last night's looks!
