Kris Jenners Two-Piece Bikini Swimsuit. Let’s add Kris Jenner in her two-piece bikini swimsuit in our list of women in their forties (and above) with fabulous fashion style. You can hate this woman all you want but you gotta admit that the matriarch of the Jenner/Kardashian clan is looking good. How old is Kris Jenner, you ask? We thought she’s, like, in her late forties but according to wikipedia she’s actually 56 years old. And she’ll be turning 57 this coming November.
