The latest image comes just one day after she attended a health bash at Annabel's in London, where she looked incredible in a black plunging jumpsuit.

The stunning one-piece had a zip going all the way down the front and showed off her incredible physique as she attended the GP Nutrition Supplements launch.  

The fashion blogger and designer's head-turning one-piece also exposed a generous glimpse of her pert breasts as she zipped the garment down below her cleavage.

She highlighted her naturally pretty facial features with warm bronze tones while her hair was coiffed in a low-maintenance style - in a middle parting and lightly tousled.

On the night, Millie caught up with her former reality show co-star Rosie Fortescue who looked incredible in a semi-sheer green crocheted dress.

She kept her modesty in tact by sporting plain black co-ords - a bandeau and a bodycon mini skirt - beneath the partially see-through number.

Rosie and Millie appeared happy to have reunited with each other as they put on a friendly display.

The girls were in good company on the night with Princess Eugenie of York, Strictly Come Dancing's Brendan Cole and James Blunt and his wife Sofia Wellesley all showing up.

The royal turned heads as she slipped into a black leather dress which was wrap-over in style.

The frock made the most of the 25-year-old's figure as a thin belt cinched her waist and the knee-skimming length allowed her legs to do the talking and the walking.
