The 28-year-old actress showed off her shorter, darker tresses at a photo call for "Teenage Mutant Ninja Turtles" in Sydney, Australia on Monday.
It looks like brunette bombshell chopped off at least six inches, and now her hair sits right at her collar bone. This is a big change for the mother-of-two, who's been rocking long, caramel ombre locks since the start of her "Turtles" tour this past July.
The sexy star paired her newly cropped 'do with a black halter tank, a black and white pencil skirt and silver peep-toe stilettos.
Before her new cut, Fox styled her long locks into a sleek braid, when she walked the carpet at the Sydney premiere on Sunday.
