The reality star is shooting new stock for her collection for Lipstick Boutique today (8 August) - and giving fans a sneak peek of her designs on Twitter.
Jess oozed glamour in her first look of the day - a skin-tight fuchsia frock featuring a pretty crochet neckline.
The brunette bombshell then posed up a storm in a ravishing one-shoulder number, complete with a delicate lace overlay.
And while Jess was busy channelling her inner sex kitten, her make-up artist Lyndsey Harrison got to work on creating a gorgeous make-up look.
Lyndsey played up Jess' eyes by applying black eyeliner to her lash line and inner waterline, before plumping her lashes with oodles of mascara.
She kept Jess' brows bold, adding a swipe of contour powder for killer cheekbones and a slick of rosy pink lippy.
And she even posted a snap showcasing all the products she used - we spy Simple Facial Cleansing Wipes, £3.25, MAC Face and Body Foundation, £21.50, a Mason Pearson hairbrush and a huge MAC eyeshadow palette!
Jess' hair was loosely curled and backcombed for heaps of body and volume, while her talons were painted a sweet Barbie pink.
With behind-the-scenes pics this good, we can't wait to see the final photographs!
