The 51-year-old has gone back to her roots and is rocking a gorgeous red all over again.
Not only that, but her lush curls are back too. Frankly, we couldn't be happier. And these shots of her on set in New York make it look like Nicole is a fan of the new style also.
That smile though!
Nicole's dramatic new look is to help her get in character for her latest project HBO's The Undoing. And her smile may simply be an act - after all, she's a professional. Given those facts, it's highly likely that when filming wraps Nic will return to the golden blonde she so clearly loves.
In the meantime, however, we will be bringing you as many pics as possible of Nicole as the redhead she was clearly born to be.
Who knows, maybe she will be inspired to keep this pretty hue? We can only hope. If you're inspired to try a colour change, have a chat with your stylist and see whether he or she thinks this a shade that might suit you.
Many salons have the technology to show you what you would look like with a whole new colour and there are plenty of apps you can try online - we like Modiface Hair Color. Alternatively, pop on a wig. It seems a little old-fashioned these days, but a wig in the colour you're considering will give you the best idea of how you will look in a brand new shade.
