Cindy Crawford "Destroyed" by Look-Alike 13-Year-Old Daughter Kaia Gerber: See the Proof!

Cindy Crawford "Destroyed" by Look-Alike 13-Year-Old Daughter Kaia Gerber: See the Proof!

The 48-year-old supermodel mama Instagrammed a picture with her 13-year-old mini-me Wednesday, and as you can see, even next to a teenager, Cindy still has that youthful glow!

It appears, too, that Kaia is clever just like her mama. In the snap, she proudly holds up a handful of property cards, and Cindy happily admits her little girl "just destroyed me in #monopoly. #oldschoolfun."

Cindy doesn't look too bothered by this loss, though. In fact, the mother of two (she and hubby Rande Gerber are also the parents of a 15-year-old son, Preston) still looks effortlessly carefree. How is that possible after all these years? It's actually pretty simple.

"The secret is that there is no secret," she revealed in a recent interview for The Violet Files. "Do all the stuff we know: Don't smoke, get enough sleep, drink plenty of water, find what makes you happy."

She stays on top of her beauty routine, too. "I use SPF day cream every day, cleanser every day and night. I definitely use the night cream, eye cream and the Crème de Serum from my line," she said. "What I think is true is that [results are] cumulative. When a 35-year-old starts taking care of her skin, she won't look different. It's when you're my age that you start seeing the payoff."

But even ageless beauties like Cindy have to fight off insecurity every now and then. "I don't want to look in the mirror every day and be down on myself," she said. "Look, I'm holding together pretty good, but I don't look like I did when I was 25 or 30 or even 40. What I'm finding for myself is that if I continue to be engaged, to do what I love, that's how I get my self-esteem cup filled. I get a lot of that from my family and work. I'm good at my job. I know I'm a good model at this point in my career. Though some days I feel like I'm too busy or too stressed out, I'm still excited to go to work. That kind of translates from the internal to the external."
