Ever since Lauren Conrad tied the knot with her hunky lawyer hubby William Tell, she's been all about trying new thangs. Case in point: The reality-babe-turned-fashion-designer had previously rocked the same hairstyle for years (like, so many years), but just last week, she got a lob (a long-bob, FYI) — and we immediately pinned it. And now, she's gone even shorter. LC's longtime hairstylist and BFF Kristin Ess spoke to InStyle about last night's cut, saying, "That front section, that piece you tuck behind your ear is the cool girl piece. It's just a tad longer than the rest of the hair and its very subtle." There you have it, laydeez. It's time to embrace the "cool girl piece" — are you down?
