Jess was unveiled as the face of the label back in January but her stunning campaign shots have just debuted.
The star can be seen working a selection of pink, nude and cream frocks in the glossy snaps with her super-full, bouncy faux locks taking centre-stage.
Her make-up's just as glam with a shiny red pout and smoky eyes.
'I am so excited to be working with Whitney Marie, their hair is super soft and so easy to put in. I love the ombre designs and how you can switch between the clip-ins or the ponytails,' raves Jess.
The brands founders Mercy and Emily Gamor seem just as happy with the star collaboration, commenting: 'Working with Jessica was an easy choice, her hair is so versatile. It looks beautiful styled up or down and she is a pleasure to work with!'
Jessica's not the first Essex starlet to make waves in the hair extensions world.
Lauren Pope's seen huge success with her label Hair Rehab London - worn by everyone from Little Mix to Cheryl Fernandez-Versini - while Frankie Essex has her own range of hairpieces called Frankie Essex Hair. Lauren Goodger's Laurens Way line includes clip-ins too.
