Cameron Diaz stuns in makeup-free selfie on Instagram about 'The Longevity Book'

It's safe to say makeup is overrated. At least that's what we think after seeing the latest picture of Cameron Diaz.

The actress took to Instagram share a makeup-free selfie that's absolutely stunning.

In a post to promote her latest project "The Longevity Book," Diaz wrote: "I'm so excited to continue the conversation because learning that you can age well, will actually help you age better."

The author, who also wrote 2013's "The Body Book," continued: "If you understand how your body works then you can take action to help keep it in the best possible condition so it can carry you through a long and beautiful life."

Diaz's new book focuses on aging both on the outside and inside and from the looks of her selfie it's safe to say the 43-year-old actress definitely knows a thing or two about getting older with grace and glamour.

This isn't the first time Diaz has put it all out there on Instagram. She's no stranger to sharing gorgeous photos of her natural, radiant look.

Hello Ladies! Happy Fall! Hope everyone is enjoying this glorious time of year; the chillier air, the changing and falling leaves; all of the markers of another year coming to a close, and a hint at the new one about to unfold. I first wanted to thank all of you who answered our call this past summer to send in any questions you might have about aging in a female body. I am so grateful for your participation, as it allowed us to address your inquries in the next volume of the @TheBodyBook. It is centered around the mental, physical and emotional journey of aging. And as we diligently put the finishing touches on the book, we’d like to ask for your help once more. This book is for you and about you and that’s why we’d like to see you on the cover. Much like the cover of the Body Book, under the jacket, were we featured women of all different shapes, sizes, builds and ethnicities. We would like for you to feel represented again, this time to show where you are in your process of aging. So we invite you to take a picture of yourself. It should look much like the one I have here; against a plain background, this general framing-you can crop closer to a portrait, and the higher-def the better! We’d like to see more of that beautiful face of yours than the body this time. And if you want to snap one with yourself and your mom and your daughter together, or any multiple generations or expressions of your journey with aging, we’d love to see those, too! And for the 50 we use on the actual cover, we’ll send you a signed copy of the book when it hits bookstores in April. So be yourself with it, be brave with it, have fun with it, and we can’t wait to see. Thank you again and Happy Selfie-ing!! Ox, Cameron To submit, click the link in my profile.

And while Diaz undeniably looks gorgeous all glammed up, there's something so refreshing about seeing a Hollywood star's bare face.
