This week Kate Moss has been partying with Lily Allen at the Dorchester and at Townhouse in London. Kate's hair is more sophisticated and sleek than when she first debuted her short cut. Meanwhile, songstress Lily Allen is showing off an edgier version of the bob. This choppy, short style looks scruffy and laid back, while the jet black colour carefully blended with espresso highlights adds shine and dimension. Whose new hairstyle do you like best?
