Green with envy!

Emma Stone flat-out owned the red carpet at the opening ceremony of the Venice Film Festival and premiere of her film "Birdman" on Aug. 27.

The actress, 25, looked stunning in an emerald tulle gown by Valentino. The full-length number featured a plunging neckline and criss-cross back and also had a knotted tie at the waist to show off her teeny figure.

While it may be easy to get lost in the loveliness of her gown, the "Amazing Spider-Man" actress also mesmerized us with a new shorter hairstyle. Her hair was inches longer when she arrived in Venice the day before with a shoulder-skimming bob. Then, for the event, Stone had chopped off inches of her auburn locks into a textured choppy 'do crafted by her main mane lady, celeb stylist Mara Roszak.

While Stone is cutting her hair, boyfriend Andrew Garfield is letting his grow. While arriving at the Italian city on Aug. 26, he showed off a full-on mountain man beard.
