Whether you're going for a full-on bob or the cut's slightly longer counterpart (a.k.a. the lob), the recent wave of above-the-shoulder crops have solidified the look as the hairstyle of the summer, and Miranda Lambert is driving the point home with her latest makeover. The musician had a lot to celebrate this week--her new album Platinum and its lead single "Automatic" debuted at the #1 spot on the Billboard charts, and Lambert celebrated by throwing a party, and showing up in a chic bob to boot. Last year, the star chopped her hair into a shoulder-skimming style, but this is the shortest we've seen her go yet. We're loving the new look.
