Not everyone ages in the same way or at the same rate, and it’s pretty amazing to see how different celebrities who are the same chronological age can appear two, three, or even sometimes ten years apart from one another.
We would have never guessed, for instance, that Taylor Momsen, and Ariana Grande were the same age (they’re both 20). Or that Diane Kruger and Melissa Joan Hart were born the same year either (amazingly, they’re both 37.)
Yet, there you go. The following gallery serves as a critical reminder why exercise, eating right, and staying out of the damn sun is key to looking young.
Take a look at our gallery of stars from ages 20 to 39, and share your tips for looking young in the comments!
