OK, we take it all back. Some people (most of them A-listers) do NOT age.
VIDEO: Over-50 Bikini Babes
Scroll down below to see 13 stars who are Benjamin Button-ing hard.
1. Jessica Alba
At 36, Jessica Alba still maintains the teenage glow she had in her early acting days. Two (going on three) kids and a beauty empire later, the ageless star is the best advert for her own company.
2. Christy Turlington
If we're using Christy as an example, 48 is the new, like, 15...? Seriously, HOW is this woman pushing 50?? If we didn't know better, we'd assume she were punking us, reverse-Younger style.
The Internet tells us that Pharrell is 44 years old, but we don't see how that's humanly possible. I mean, yeah, I guess we'd be "Happy" too if we never physically aged...
4. Reese Witherspoon
No, neither of these images is of Reese's teenage daughter Ava.
5. Gabrielle Union
Two truths and a lie: Gabrielle Union guest-starred on Friends; Gabrielle Union is from Nebraska; Gabrielle Union is turning 30 this year (SPOILER: this is the lie, she's turning 45!). Mind = blown.
6. Will Smith
Fresh as ever, Will Smith turns 49 this year.
8. Gwen Stefani
While she claims she's "just a girl," this is totally false—she's a kick-ass, ab-baring mother of three who hasn't visibly aged since the late '90s.
9. Jennifer Aniston
Fearless, fabulous, and 48, the Friends alum maintains the youthful spunk of her Rachel Green days.
10. Halle Berry
Somewhere in Los Angeles, the Oscar winner is making daily pilgrimages to sip from a fountain of youth—it's the only viable explanation.
11. Jennifer Lopez
Before Brad Pitt starred in the movie, J.Lo was the O.G. Benjamin Button.
12. Paul Rudd
The Ant-Man star may be 48 in years, but in our hearts he'll always be Cher's dorky 20-something stepbrother.
13. Kerry Washington
The Scandal star is flawless at any age (not that we can actually tell the difference).
