Many people go short when the weather turns warm, but for some stars, it's just the opposite. Emma Roberts recently chopped off several inches of her signature long strands in a move reportedly inspired by Jennifer Aniston's lob. Cameron Diaz and Penelope Cruz have also joined the tousled bob brigade, both debuting wavy, lightly layered looks within the past few weeks. It's easy to see why all three women have made the change. Not only is the style a chic, modern way to wear the classic cut, but because of its longer length, the styling options are practically endless.
