Dianna Agron New Haircut. Glee star Dianna recently cut her long locks into a head turning bob style. Her new haircut consists of layers that frame the stars face and gently makes her cheekbones pop. The cut still allows her to have a sexy side swept bang that grazes her left eye, but her new cut is much more mature than her previously style. It will be interesting to see how the star wears her new haircut styled in the Fall for new years Glee Season. Look below to see her new cut.
