Charlize Theron has been hitting red carpets all over the world to promote her two films, Prometheus and Snow White and the Huntsman. The actress, however, now looks significantly different from the way she looked at those premieres; She’s still got her stellar sense of style, but her golden locks are now missing.

Theron was spotted sporting a shaved head hidden under a bowler hat while walking around Beverly Hills with her 6-month-old son Jackson on Monday.

The actress shaved her head for her role in upcoming action film, Mad Max: Fury Road, a rep confirmed to The Hollywood Reporter. Theron will play Furiosa in the long-delayed project, which is set to start filming this summer in Namibia, Africa. Directed by George Miller, the fourth film in the franchise also stars Tom Hardy.

Theron, who’s been attached to the project since 2009, has changed her physical appearance for a film before. For 2003’s Monster, she gained about 30 pounds, had her eyebroys partially shaved and bleached and wore prosthetic dentures to push out her mouth slightly.
