While we've always known the Atomic Kitten singer as a fiery redhead, she kicked off 2015 with a bang by opting for a pretty dramatic image overhaul.
Natasha - who welcomed baby girl Ella with partner Ritchie Neville in September 2014 - looked glowing and radiant while launching The Big Boxtrolls Recycling Week Challenge at a primary school in Manchester.
The yummy mummy opted for a very sophisticated new 'do, swapping her pretty strawberry strands for a deep chestnut hue while ditching the highlights for a uniform look.
Her bonce was styled in a middle parting with the lengths perfectly-coiffed into a sleek yet bouncy blow-dry boasting heaps of volume.
To complement her darker tresses, Natasha kept her make-up bold with a thick slick of liquid liner running across her upper lashlines for a doe-eyed effect.
She perked up her English rose complexion with a sweep of warm pink blusher, completing her look by plumping up her lips with raspberry pink matte lipstick.
We reckon Natasha always looks lovely, but we're particularly loving this smouldering new hue on her. We're even tempted to dye our locks too...
Family animation adventure of The Boxtrolls is out now on 3D Blu-ray and DVD.
