Some people have compared her new hairstyle to Taylor Swift's platinum blonde bob, reported Aceshowbiz.
In some photos that surfaced online, Stone, 27, kept it casual in a black long-sleeved tee paired with ripped high-waist jeans and leopard print flats.
The "Birdman" actress completed her look with black sunglasses and a tan cross-body bag.
It is unclear if Emma's new hairstyle is for an acting part.
