If there's one man on earth who can make us love a mullet and and chin-strap goatee, it might be the cuddly Avengers star (who posted this charming shot in support of young people getting vaccinated).
Jeff Goldblum

Incredible vintage photos of the Jurassic Park star will always find a way to surface on the internet.
Jimmy Fallon

Sure, he had a mullet and high-waisted acid-washed jeans, but that was be-FORE! (Get it?)
The Jonas Brothers

We're a sucker for the JoBros, so it would honestly be unfair to single out Kevin, Joe or Nick's awkward phases. The brothers have grown up before our eyes, and their collective glow-up (cough cough, Nick's arms) has been a sight to behold. But we will never forget this 2008 look: pocket squares, sunglasses and extreme color-coordination. Iconic.
Adam Levine

Anyone else finding it a little "Harder to Breathe" looking at this throwback photo of the Maroon 5 frontman? Long before he was showing off his tattooed, chiseled chest during the Super Bowl Halftime Show, Levine was focusing his energy on growing this, um, questionable goatee. "1996 in the house. That HARRIBLE 90s goatee took me an entire summer to grow," he revealed on Instagram.
Tom Brady

We're just over here thanking the hot athlete heavens he kept getting better-looking after basketball practice.
Val Chmerkovskiy

The Dancing with the Stars pro made sure everyone knew he was big pimpin' at a young age — a move he now regrets. "We all make mistakes ... but no mistake was greater than that of the 15yo me deciding to compose this fashion statement for my 10th grade yearbook picture," he wrote on Instagram.
Joe Manganiello
:max_bytes(150000):strip_icc():focal(216x0:218x2)/joe-manganiello1-1bb52441d8f44843b24d778f083a9060.jpg)
This 1996 peroxide situation is simply traumatizing – and don't even get us started on that little patch under his lower lip. Even Manganiello's True Blood costar Anna Paquin was rendered nearly speechless at the sight of his pre-millennium mistakes.
George Clooney
:max_bytes(150000):strip_icc():focal(776x0:778x2)/george-clooney2-2000-1e1f676379194cfb9a63ef3147888dc0.jpg)
It may have been brief, but Clooney did, in fact, go through an awkward phase as a young'n.
Drake Bell & Josh Peck
:max_bytes(150000):strip_icc():focal(623x0:625x2)/drake-bell-josh-peck-2000-9bfb072fbbd042dc90ad2aad53b4e947.jpg)
The nice thing about starring on a sitcom in your teen years with a buddy? You go through your awkward phases together.
Dwayne 'The Rock' Johnson
:max_bytes(150000):strip_icc():focal(299x0:301x2)/the-rock1-9e37d6f29bba4006aead21eb8a39e775.jpg)
The actor described this as an "iconic and horrendous hot garbage of a pic" on Instagram. We couldn't have said it better ourselves. Let his very bold '90s choices be a reminder that sometimes it's best to just play it safe.
Zac Efron
:max_bytes(150000):strip_icc():focal(327x0:329x2)/zac-efron-1bf3c240f71a4112812e29e5b94d051b.jpg)
Who let this child get his hands on a crimper? And who inflicted that middle part on his poor innocent soul?
Justin Bieber
:max_bytes(150000):strip_icc():focal(651x0:653x2)/justin-bieber2-1-577b714ef35b48ff9102c807fe02e0f4.jpg)
Before Bieber had muscles or a mustache, he was a beloved, "Baby"-faced teen whose swoopy hairstyle took over middle schools across the country.
David Beckham

The 2015 Sexiest Man Alive has done a lot of questionable things to his hair throughout the years, and this 1997 thing is no exception.
Chris Pratt
:max_bytes(150000):strip_icc():focal(299x0:301x2)/chris-pratt-3-079efef7fa8c45a69918f249a1f53e7f.jpg)
The world had to endure the sideburn-donning McChest showcased in Pratt's first-ever headshot so it could earn the chiseled superstar we have today. Just remember that when this bro-tastic image catches you off-guard.
Drake
:max_bytes(150000):strip_icc():focal(521x0:523x2)/drake1-6e48879453eb4498b72ce7273105933a.jpg)
Drake clearly has a sense of humor about his wayward teenage style, and apparently so did his parents when they let him leave the house in those unflattering frames.
Colton Haynes
:max_bytes(150000):strip_icc():focal(523x0:525x2)/colton-hayes-6804eb24e3c44d0cb62766780d8b00e5.jpg)
"High school continues to haunt me forever," Haynes captioned his yearbook shame. Same here, Haynes, same here.
Ewan McGregor
:max_bytes(150000):strip_icc():focal(792x0:794x2)/ewan-mcgregor-1-2000-e879cd35217742cda6bca73db04c4f1a.jpg)
McGregor weathered some interesting bangs before blossoming into the heartthrob we know today.
