The This Morning's Hub presenter mixed things up by dying her tumbling caramel locks a touch darker, opting for a lush shade of chestnut brown.
Zoe revealed her sultry new barnet while attending the pre-Wimbledon party at Kensington Roof Gardens yesterday (20 June), wearing a white shirt buttoned to the top and a statement gold necklace.
And it's not only her hair colour that's changed - the starlet has been switching things up in the lip department too!
We've already spotted her rocking mega-loud neon lips and an exotic orange pout, but this time Zoe donned a glossy shade of pink.
She added her signature black liner, bold voluminous lashes, and a wash of rosy cream blush on the apples of her cheeks.
