However, no doubt most will be focused on her incredible abs as Kate showed off her taut figure in a white bandeau.

She teamed the showy top with a pair of black cropped trousers with white stars all over it along with a sweater featuring a white and black ombre with cheetah print. 

Kate captioned the image with a cheeky message to her 4.9million followers: 'We heard a noise.'

Her most recent Instagram post comes just three days after she took to Instagram on Sunday to share a smoldering slew of videos where she and a gal pal posed up a storm in sexy medieval armour costumes.

The model showed off her enviable frame and toned pins in the high-rising black number, complete with an opulent red-and-gold cape she joked about having a low cleavage. 

The corset-style outfit accentuated the star's slim waist and featured gold detailing, complete with onyx feathers and leather straps in its bottom half.

The Much Ado About Nothing actress had tied her caramel tresses into an enormous bun and cupped her assets while joking, 'In relation to your real boobs, where are yours cos mine are here?' while gesturing downwards.

Kate wrote in the post's caption: 'Happy birthday @nina_kate. Not sure what the f*** I thought I was doing before I met you. Best girl best Sainsbury’s bag best ever xxx.' 

The pals shot their best power poses towards the camera while joking that they were about to 'pillage a town' in their medieval suits.

Orange-haired Nina sported a stylish buzzcut and showed off her vast collection of tattoos in the skin-exposing ensemble.

She elevated her height in a chunky pair of glossy black shin-high lace-up heels, while Kate co-ordinated her strapped gold heels with her costume.

After the photoshoot came to an end, the Underworld actress strutted her way out of the camera's shot - but not before stumbling over her own feet while doing so.

'Just the level of encouragement when one is not feeling very pillagey and is a bit tired is why you are my favourite, @nina_kate,' the SAG Award nominee wrote in a follow-up caption.
