10+ Of 2020's Most Famous Celebs Who Looked Very Different 10 Years Ago

Margot Robbie got her start on an Australian soap opera called Neighbours.

You can see how she was still just a kid when she was starting out. I personally prefer Margot's Harley look, but I'm about as biased as they come.

Watch out, world, because Timothée Chalamet is here to stay! What many people don't realize is that Timothée got his start on the Hallmark Channel.

For my money, he and Robert Pattinson are two of the greatest character actors I've ever seen.

Most of us know Millie from her breakthrough role as Eleven in Netflix's Stranger Things.

But before she ever achieved international stardom, she was cast as Young Alice in Once Upon A Time in Wonderland.

I have such a hard time picturing Letitia Wright with long hair. She is beautiful either way, don't get me wrong, but her short hair suits her so much better.

She began her journey to Wakanda on the set of Top Boy.

Oh, the "emo-swoop" — what a glorious haircut it was! Zac's facial hair nowadays is something to behold as well. I bet you he could grow a beard in 45 minutes flat from pure force of will.

He's also a full-bound muscle machine, as you can see on his new series Down to Earth with Zac Efron.

I love Wes Anderson. There is just something about his film aesthetic, the subtle dry humor, and his ability to tell stories that I find captivating.

It was on Wes Anderson's Moonrise Kingdom that Lucas made his starring film debut! More recently, he appeared in Shia LaBeouf's Honey Boy.

Many of us watched Maisie Williams grow up right before our eyes, and to many, she will always be Arya Stark.

Her beloved character is certainly in stark contrast with the beautiful young woman Maisie has become.

Miley spent her tween years carefully building and crafting an image. She then spent the bulk of her late teens and 20s trying to cast off the Disney channel shackles.

I personally prefer Miley with short hair. How about you?

Robert Pattinson has been a busy man. He's spent the better part of a decade trying to free himself from the shadows of Twilight, and I'm pleased to say that he is succeeding!

I can't wait to see Robert in Matt Reeves' The Batman.

You heard it here first — Saoirse Ronan is the greatest actress of the decade. She has the potential to be one of the greatest of all time, having already racked up four Academy Award nominations.

She is not the little girl from The Lovely Bones anymore.

Brie Larson is one of the most important women in the genre of comic book filmmaking. She has been championing female heroes since her days on the set of Scott Pilgrim vs. The World.

Here's hoping we won't have to wait too long to see the Captain Marvel sequel.

If Pattinson and Chalamet are the greatest character actors of our time, Shia LaBeouf may just be the best method actor — or at the very least, the most insane.

For his role in The Tax Collector, Shia tattooed his entire body.

Long before Tom Holland swung his way into our hearts and minds as Spider-Man, he acted opposite Naomi Watts and Ewan McGregor in a film called The Impossible.

Was Tom a cute-looking kid or what? I guess some things don't change.

Long before One Direction, Harry Styles was introduced to the world as a contestant on The X Factor.

Not only has Harry grown up in the last 10 years, but he's also become one of pop music's most sought-after young talents.

I think that Rebel Wilson is one of, if not the, funniest woman in Hollywood. Her self-deprecating humor combined with a sheer lust for life put Rebel in a category all her own.

Her body transformation and dedication to personal fitness over the last decade is inspiring.

Chris Evans seems to have gone through a physical transformation and a performative one over the last 10 years.

He catapulted himself into major stardom thanks to being in the MCU and taking on amazing scripts such as Knives Out.

Ten years ago, he also didn't have the massive bulk that came with playing Captain America, and he seems to greatly appreciate a full-grown beard now.

There are not too many photos of Kylie Jenner from 10 years ago, but once you find them, you can really see how much the star has changed.

Not just physically, either. She is now a mother!

Ten years ago, Justin Bieber started a haircut movement like the world hadn't seen since Jennifer Aniston's Rachel Green look.

Since then, he has moved on and gotten tattoos, longer hair, and is even married!

Chris Pratt lost a lot of weight in order to play the part of Star-Lord in Guardians of the Galaxy.

Like Chris Evans, his professional career looks a lot different now than it did 10 years ago, thanks to the MCU.

This Kardashian has gone through a lot in her personal life, but she doesn't make it stop her!

Over the past 10 years, the star has made it a point to be a healthier person and has ditched the brown locks for blonde.

This pop star queen has gone through a lot more than most people and has come out the other side as an absolute queen.

She started out on a show and is now one of the biggest stars in the world. And, tbh, she definitely works the brown and blonde hair a lot better than the red.

Cole Sprouse has gone from a child Disney channel star to a young adult working for The CW, one of the biggest TV networks in the world.

He has a lot more swagger now, and fans adore him because of it.

Like her sisters, Kendall has gone through plenty of changes over the past 10 years. She has always remained STUNNING.

I wonder if Kendall ever thought she would be one of the most famous and wanted models in the world...

This star has recently lost 85 pounds! She has definitely earned her bragging rights!

The one thing that hasn't changed about her is that she loves to color her hair in bright shades!

Adele shocked fans everywhere when she revealed her weight loss on Instagram in a stunning photo.

But let's be clear about something: She has always been beautiful, regardless of how much she weighs!
