Margot Robbie has ditched her trademark blonde hair - you have to see it to believe it!

Margot Robbie's new brunette hair has taken fans (that includes us) by surprise. Some celebrities (Kim Kardashian we're looking at you) have changed their hair color and style at the drop of a hat during quarantine. But Margot has stayed pretty consistent, going just a few shades darker blonde at the end of last year. 

But now that filming has resumed in Hollywood, Robbie is reminding us just what a hair colour chameleon she can be.

The 30 year-old The Birds of Prey actor was spotted on set for her new film with director David O.Russell sporting a dark brunette shade instead of her signature gold blonde locks.

Robbie could not look more different with side-parted, flicked out waves reminiscent of Hollywood's classic starlets, dark brows and still darker eye makeup.

Of course, this isn't the first time Robbie has opted for a brunette shade. She stunned in a glossy chocolate hue and shoulder-skimming  waves at the Academy Awards in 2014. That same year she worked strawberry blonde hair to perfection, too.

Robbie is joined by Christian Bale, Robert de Niro and Zoe Saldana on the as yet untitled movie and proves that it isn't just blondes who have all the fun.
