Lauren Conrad the hills dress jacket autographs

...and we like it!

LC usually keeps her locks long and wavy, but last night she decided to experiment with a sexy updo. The former Hills hottie snuck out the back of Hollywood hotspot MyStudio with bf Kyle Howard, and not only are we loving her look, but the smile really completes her outfit, don't ya think? How refreshing it is to see her in such a chipper mood!
