Some good things may come to end, but Cindy Crawford's good looks aren't one of them. The supermodel mom looks more gorgeous than ever, something she proved with her latest selfie. Crawford took to Instagram on Monday to share a photo of herself with no makeup on, and it has us begging the question: Cindy, what is your secret?

In the 'gram, Crawford smiled at the camera, her hair looking perfectly coifed although it appears she's in bed. Crawford is in Miami, where she is promoting her new book, Becoming Cindy. The model-turned-author has shared several photos from her trip, including pictures with fans as well as a 'gram of her morning coffee (along with some stunning scenery).
