And some people are such fans of Cruella's black and white contrasted hair that they too have given their locks an incredible makeover - and we love the effect.
The trendy hairstyle splits right down the middle, giving a contrasting look so synonymous with the Disney character - and it looks equally as great on short or longer hair.
Think of it as a colourblock effect, but for your hair.
Take a look at some examples below:
From Kate Merlot's vintage-inspired locks to Aaron Baker's modern take on the trend, the results are stunning.
While Kayla Smith's take on the hairstyle proves that it works just as well on longer hair too.
We love Siân's more subtle Cruella-inspired hair.
And this platinum blonde hair, by Jennalee, is perfectly contrasted with a dark brown.
So, how on earth can you achieve this black and white hair colour for yourself?
Tyla spoke to hair stylist Nikita Fisher from Palmer Fisher London, who gave us some hot tips on how to get the Cruella look in the salon.
Nikita says she's seen this technique used in just about every colour you can imagine, from softer pastel tones to darker colour variations, and she loves it.
"For anyone looking to achieve this look, especially in darker colour variations like black and white, you need to find the right hairdresser, preferably a colour expert who isn't afraid of a challenge," says Nikita. "It is also important to remember that you need to have the right base to achieve such bold colours which can be a lengthy process."
She advises that this step alone can take a few sittings.
Instagram, Nikita adds, is a great place to find colour experts perfectly suited to creating this unique style.
"Once you have found one you love you should book in for an in-salon consultation so you can discuss your goal and your hairdresser can understand what they are working with.
"If this isn't possible, send them a pic of the look you are trying to create as well as a pic of your hair now in natural daylight, this should give them enough to give you a rough idea of what is achievable and in how many sittings."
Nikita adds that this look can only really be achieved in a hairdressers, as it could go wrong if done at home.
She advises: "I certainly wouldn't advise trying this sort of bold look at home. Even as professional hairdressers we know that putting black next to white hair could quite easily turn into a disaster."
And once you have your dream hair colour? "You need to make sure you look after it at home," Nikita advises. "Any professional colourist will recommend products that work alongside the colour products they have used, and although they may be pricier than the products in the supermarket, they are totally worth it, trust us!"
For a long-lasting colour, Nikita says that it's important not to wash your hair in really hot water, or wash it too often, and sticking to the rules will guarantee its longevity.
The hair stylist adds that this colour is perfect for creatives who want to express themselves with a new style.
She says: "I absolutely love the two-toned trend and it can be quite versatile in many ways.
"It's perfect for indecisive creative characters who aren't scared of trying something new and daring," she enthuses. "I think we will see a lot more of the two-toned trend in 2021 and personally, I can't wait. Bring it on!"
If you want to try out a pastel version of the trend instead, Nikita adds that she loves the look in softer pastel tones worked on a pre toned white-blonde base, "splitting the hair right down the centre and colouring one side pastel - amazing!"
We couldn't agree more.
The only question now is to decide which side will be light and which side dark.
