The 38-year-old actress shaved off her famous long blonde locks for the flick, which comes from Australian singer/songwriter Sia — who also wrote and is directing the project.
It’s the most drastic haircut Hudson has had since she found breakout success in 2000’s Almost Famous.
The actress took to her Instagram shortly after the news broke to debut the look, thanking Sia for the “freedom” and calling her “our beautiful director.”
It also makes the Fabletics mogul look even more like her mother Goldie Hawn, who rocked a longer pixie cut in the ’60s and ’70s while she starred in projects like andRowan & Martin’s Laugh-In and Cactus Flower.
Of course, Hudson isn’t the first actress in Hollywood to shave her head for a role.
Demi Moore, Cara Delevingne, Charlize Theron, Anne Hathaway and Angelina Jolie are just a few of the stars who have chopped it all of for the cameras.
Singers like Halsey and Jessie J have also rocked the buzzed look.
