Ahh, the battle of the blazer-clad blondes!

Last night we spotted Lauren Conrad leaving the Elder Scrolls V: Skyrim launch party in Los Angeles (you know, because she just LOVES to stay relevant video games), and earlier in the day we caught her former Hills co-star Kristin Cavallari smiling as she shopped at the Grove in Los Angeles. LC rocked black skinny pants and pumps with her off-white jacket while KC opted for grey suede Louboutin booties and a short dress that showed off her sexy legs.

We hate to pit these two frenemies against one another, but we HAVE to ask...
