Celebrities Who Looked Exactly The Same When They Were 20 And 30 Years Old

Time catches up to us all. No matter how hard we fight it, sooner or later we all begin to lose our once youthful looks. Well, almost all of us.

There are some celebrities who it would appear have taken a large gulp from the fountain of youth.

See what I mean and check out these celebrities who literally looked exactly the same when they were 20 and 30.

Jared Leto.

ABC / Lionsgate

Jared Leto not only looks the same, but he's also managed to somehow keep the exact hairstyle over a ten-year period.

There aren't many who could make a look like this timeless, but Jared is certainly one of them.

Joseph Gordon-Levitt

TLSA Releasing / Warner Bros.

I absolutely adore Joseph Gordon-Levitt's body of work. Not only is 3rd Rock From the Sun one of my all-time favorite TV shows, I'm also a sucker for 10 Things I Hate About You.

But who isn't, am I right?

Jennifer Aniston.

TriMark Pictures / Universal Pictures

If you're looking for a fun scare (and a decent laugh) you absolutely have to check out Jennifer Aniston in Leprachaun.

It was her feature film debut and a classic ode to the horror tropes of the early '90s.

Will Smith.

NBC / Sony Pictures

I'd be willing to bet money that if you photoshopped the hat that Will is wearing in the image on the left onto the image on the right, that not a single person would be able to tell the difference.

Ashton Kutcher.

Fox / Paramount Pictures

What was it that I was just mentioning about goofy-looking hats?

Aside from the noticeably shorter hair, Ashton hasn't aged a minute. Even today he possesses the same youthful exuberance that he always has.

I sure do wish he'd come back to Shark Tank...

Mila Kunis.

Fox / Disney

The children of Mila and Ashton are going to have incredibly strong genes when it comes to looking youthful.

These two must sleep in an oxygen tent because that's the only explanation I can muster as to how they manage to look as good as they do.

Angelina Jolie.

MGM / 20th Century Fox

I can almost guarantee that the majority of you haven't seen Angelina's film debut, Hackers.

And while I'll admit that there are elements that haven't exactly aged well, it's still well worth the watch. "Mess with the best, die like the rest..."

Paul Rudd.

Paramount Pictures / Universal Pictures

Could it be that Paul Rudd is actually a time traveler? That what he's really doing is inserting himself at scattered points throughout our collective timeline?

I'm not saying my theory doesn't have holes, but it's one explanation...

Gabrielle Union.

Miramax Films / Screen Gems

I actually had a pretty big crush on Gabrielle Union after I saw She's All That. And again when I saw Bring it On; 10 Things I Hate About You — you get the point.

She's as gorgeous today as she was nearly 25 years ago.

Keanu Reeves.

Orion Pictures / Warner Bros.

The Keanu on the left is reacting to the situation being experienced by the Keanu on the right. "There is no spoon" — what a revelation that was!

On a scale of 1-10, how excited are you for Neo's return in The Matrix 4?!

Halle Berry.

Warner Bros. / Warner Bros.

Halle is just too beautiful for words. For the better part of the past two decades, she also seems to be aging in reverse.

I don't know what her secret is, but clearly, she's got it all figured out.

Cameron Diaz.

New Line Cinema / 20th Century Fox

Cameron Diaz had every single man on the planet exclaiming "Smokin'!" from the moment she walked into the frame in The Mask.

She continues to set the standard for timeless beauty, even to this very day. We love you 3000, Cameron!

Brad Pitt.

Sony Pictures / Warner Bros.

The only thing that seems to have changed from the time Brad Pitt was in his 20s until his 30s, was that he managed to get even more handsome, jacked, and tan.

We should all be so unfortunate.

Michael Cera.

Fox / Destination Films

Michael Cera's appearance seems to be in a state of Arrested Development. Due to his boyish charms, he often gets typecast as the awkward, nerdy introvert.

And while there's no denying he excels at this character type, to presume he has nothing else to offer would be an error in judgment.

Reese Witherspoon.

Universal Pictures / Summit Entertainment

What's even scarier than the fact that Reese Witherspoon hasn't aged a day in literally more than 30 years, is how much her daughter resembles her.

I'm being dead serious — in the right light, you'd swear that Ava was her mother.
