Unlike us regular folk, celebrities have the power to drastically transform themselves.

But the real kicker?

These celebs didn’t take very long to complete their metamorphoses.

Kylie Jenner 2018

In fact, some of them are downright unrecognizable fromjustfive years ago.

How is that possible?

So who out there lost so much weight that they’re just a shadow of their former selves?

June Shannon 2013/June Shannon 2018

Who’s gone under the knife to go from not to hot?

And who has made major changes that have empowered them to truly live their best lives?

Check out these celebs who are pretty much unrecognizable from a mere five years ago.

Justin Bieber 2013/Justin Bieber 2018

She was loud, she was large, and she wasdefinitelycontroversial but also, arguably, authentic.

Fast-forward five years later, and Shannonlooks like a totally different person.

We think she looks amazing!

Caitlyn Jenner 2013/Caitlyn Jenner 2018

Looks like Shannon’s been laughing at her haters all the way to the bank!

Also, his wardrobe was still relatively clean-cut.

And his100 hours of tattooingwere mostly still in front of him.

Kevin Smith 2013/Kevin Smith 2018

You do you, boo.

It’s amazing she can finally be herself!

“I’m still the same person.

Renee Zellweger 2013/Renee Zellweger 2018

Caitlyn lived inside me all my life.”

And that had consequences.

That’s when he cut out sugary drinks and began to walk regularly, in earnest.

Zach Galifianakis 2013/Zach Galifianakis 2018

Then the weight began “flying off.”

Then in early 2018, Smith survived a heart attack often called the “widow maker.”

But Smith’s perspective is not what you might expect.

Kylie Jenner 2013/Kylie Jenner 2018

He’s made plans tostep uphis workout game, too!

She evenwonthe Academy Award for Best Supporting Actress for her role in 2003’sCold Mountain.

She was definitely an It girl, known for her wholesome look and trademark, squinty eyes.

Penn Jillette 2013/Penn Jillette 2018

Clearly she was not afraid to stand up for herself.

Zellweger has since moved on from the gossip, according toPeoplemagazine, and is focusing on her own life.

Way to handle the haters with grace!

Missy Elliott 2014/Missy Elliott 2018

That was not the beginning of Galifianakis' transformation, though it had certainly ramped up by then.

But by no means was he finished yet.

He also made changes to his eating habits, which helped him drop even more excess weight.

John Goodman 2013/John Goodman 2018

He went on to make jokes about cutting out “whipped cream pizzas” as well.

But we’re not here to hate, as Jenner could slay in her sleep.

And while she’s admitted to having her looks enhanced, it’s been on her own terms.

“I have temporary lip fillers,” she confessed onKeeping Up With The Kardashians.

“It’s just an insecurity of mine and it’s what I wanted to do.”

Hands up if you’re all in favor of a woman doing what she wants.

Girl, you do you and don’t listen to the noise.

The change has rendered him unrecognizable from the portly, pony-tailed man he used to be five years ago.

“My doctor said I needed to get my weight down,” he shared in an interview withPeoplemagazine.

Sounds like magic to us!

That diet reset Jillette’s palate, completely changing his approach to food.

Thanks to the changes, he feels fantastic in his new skin.

And yes the ponytail’s gone too!

For one, back in 2014, the singer confirmed that she had been slimming down.

So what was her reason, then?

“I wanted to be in good health for my shows,” she revealed.

And while she admits she still craves junk food (who doesn’t?

), she’s developed a solid workout regimen and has stuck to it.

And that’s not all, either.

No wonder her skin is absolutely perfect!

“It just bothers me.”

Those remarks came after he had started his weight loss (and sobriety!)

So how did he do it?

Rock on, John!
