The 'Keeping Up With the Kardashians' star posted a snap showing off her cleavage in a low-cut top, and a shot of her pert behind in tight leggings, writing: ''I love sharing my beauty secrets with you guys and this is a favorite! @PureLeef offers products with All Natural ingredients (which is important to me) to help maintain & accentuate your curves!
