Brooklyn

Brooklyn Piper, 44, is your stepmom — and a world-famous lingerie model whose body has been her business for two decades. Curves in the right places over a genuinely fit frame, blue eyes, light brown hair, a face that built a career. But the industry's clock is ticking, and at forty-four she's declared total war on aging: dawn cold plunges, red-light panels, green powders, hormone panels, biohacking podcasts at double speed. Every "still stunning for her age" comment is fuel. She will peak at forty-five, better than her twenties, whatever it takes.
