1. John Stamos
Media Source
The only thing that has changed about John Stamos is that he dumped the mullet. That's fine, as long as he never dumps Aunt Becky.
2. Jessica Biel
Media Source
Jessica Biel is as wrinkle-free as her 7th Heaven days.
3. Jared Leto
Media Source
Nowadays he's sporting longer hair, but his face is the same. And we still swoon like Angela Chase.
4. Joseph Gordon-Levitt
Media Source
He was a cutie on 3rd Rock from the Sun and he's a cutie now. He must have learned the secret to youth from the Big Giant Head.
5. Julia Stiles
Media Source
For Julia Stiles, every day is 1999 because she hasn't aged since 10 Things I Hate About You.
6. Ewan McGregor
Media Source
The Force is strong with this one, but the handsomeness is even stronger. Ewan McGregor looks just as good as he did during Star Wars Episode 1.
7. Brad Pitt
Media Source
Brad Pitt won the genetic lottery. This year he's turning fifty-one.
8. Beyonce
Media Source
Her style has changed, but her face certainly has not. She may be Sasha Fierce, but she's easy on the eyes.
9. Keanu Reeves
Media Source
Keanu is a Polynesian/Hawaiian name, which either means "Cool mountain breeze" or "IMMORTAL!"
10. Rob Lowe
Media Source
The Parks and Recreation star "literally" looks the same. Probably from following the Chris Traeger diet.
11. Maggie Smith
Media Source
Apparently playing Professor McGonagall taught Maggie Smith how to use Transfiguration to stay the same looking.
12. Sean Connery
Media Source
Sean Connery reached his maximum form in Indiana Jones and the Last Crusade and hasn't changed since. He chose...wisely.
13. Steve Martin
Media Source
Steve Martin's hair went white in his early 30's, and he's basically looked exactly the same ever since (Plus or minus an arrow through his head).
14. Paul Rudd
Media Source
What's Paul Rudd's secret to perpetual youth? We're clueless.
15. Patrick Stewart
Media Source
Star Trek got a lot of things right about the future, like video calling and tablets. But here's one thing we're glad they got wrong.
