Emma Reveals Bob–Actress Emma Stone is the latest star to shorn her tresses into a bob haircut. The redhead beauty debuted the look at the “Birdman” premiere at the annual Venice Film Festival in Italy earlier today. Emma wore a Valentino fall 2014 haute couture gown in a complementary green hue designed in tulle on the red carpet. What do you think of Emma’s new hairdo? She just revealed bangs a few months earlier. Presumably, the hairstyle is for her upcoming turn on Broadway in “Cabaret”.
