The 57-year-old Keeping Up With the Kardashians matriarch posted a picture of herself waist-deep in a pool on Sunday, Sept. 15. In it, she wears nothing but a cleavage-baring blue bikini and a chunky gold necklace. Her short dark hair is slicked back, and her face is fully made up with black eyeliner and bright pink lip gloss. Damn!!! she looks so hooot!!!
