Lily Collins and Karlie Kloss have been keeping their hairstylists busy! Over the weekend, Collins chopped her long bob into a chin-grazing version, while Kloss debuted a golden blonde hue. Collins—who, as far as we're concerned, is the spokesperson for perfect eyebrows—has worn her strands in a shoulder-skimming cut ever since last year, but was spotted out in a much shorter style that's just as flattering and is perfect for the rising temps. The bob movement has been gaining popularity in Hollywood recently, and the star is in good company, joining Mindy Kaling, Jennifer Aniston, Emma Stone, Jennifer Love Hewitt, and many others taking on the trend.

Kloss is always game for a spontaneous hair change. At the Victoria's Secret fashion show in 2012, the supermodel surprised hairstylist Orlando Pita (as well as us!) by debuting a long bob only hours before the show began. But thanks to some quick thinking and well-placed extensions by Pita, her look stayed in-line with the waves worn by the rest of the Angels on the runway. At first glance, we almost thought the Instagram the model posted of her new look was a picture of her friend Taylor Swift. But whether or not Kloss used her BFF as inspiration, she pulls off her new hue like a pro.
