Her photo revealed the reality star's pert posterior as she sat on the edge of a bed - seemingly wearing just a bra.

"#secretproject coming soon," was all she wrote as a caption, before tagging the fashion photographers Mert and Marcus.

That's a cheeky shot

The famed art duo - Mert Alas and Marcus Piggot - have shot the likes of Madonna and Kate Moss for numerous publications such as Vogue, Love magazine and W.

Another shot, posted to their official account, appeared to tease a full cleavage shot of the star, as she shielded her nipples with her hands.

"GUESS WHO #secretproject coming soon #mertandmarcus," read the caption.
