This is the surprising reason why Kate Hudson has shaved her head

We didn’t see that coming…

Ever since Kate Hudson first graced our screens in the 2000 classic Almost Famous, she has been known for her signature hairstyle, with long blonde locks becoming her trademark look.

Whether starring as Andie Anderson in How to Lose a Guy in Ten Days or as Helen Harris in Raising Helen, her long blonde hair has been a constant.

However, the 38-year-old actress has made a big change just this week, debuting a brand new look that we definitely didn’t see coming.

Saying goodbye to her trademark blonde hair, Kate has traded in for a buzz cut, shaving her head earlier this week.

While Kate’s bold hair change has come as a shock to fans, it certainly wasn’t a rash decision, with the actress choosing to sacrifice her locks for a film role.

Kate is currently filming for Sisters, a feature set for release in 2018 co-written and directed by Australian singer-songwriter Sia.

Taking to her Instagram, Kate shared a film still from Sisters, captioning the snap: ‘Freedom. Compliments of @siathisisacting #OurBeautifulDirector’.

Her fans have been loving the stunning new look, with one user commenting ‘Just when I thought I couldn’t love you any more!’ whilst another commented on the ‘perfect shape’ of Kate’s head, telling her how beautiful she looked.

Sisters will also star Maddie Ziegler, the 14-year-old dancer who has worked closely with Sia before on multiple projects, starring in her music videos for Chandelier, The Greatest, Cheap Thrills, Elastic Heart and Big Girls Cry.

Kate Hudson, Sia and Maddie Ziegler – that's a pretty great combination. 2018 can't come sooner!
