Before they were performing for thousands of people on stage or stealing our hearts on screen, your favorite celebrities were normal people just like you and me! Yep, most of them attended school like the rest of us, and boy, did they look different back then.

Take Harry Styles, for example. One of the One Direction member’s former classmates just shared his old yearbook picture on TikTok, and we cannot get over how much he has changed since his high school days!

This got us thinking — what did our other favorite stars look like in school?! We went ahead and rounded up the yearbook photos of some of Hollywood’s biggest celebrities, so prepare to be shook over their glo’ ups.

Taylor Swift

Can we please talk about how adorable Taylor Swift looked when she was in high school?! This was from her sophomore year — little did she know, she would soon become one of the most famous people in the world!

Ariana Grande

We almost didn’t recognize Ariana Grande without her signature long ponytail! Yep, before landing her role on Victorious as Cat Valentine and becoming a megastar, she looked totally different.

Camila Cabello

Can anyone guess who this is? Drum roll please… It’s Camila Cabello! Wow, the brunette beauty had a major glo’ up between her school days and when she auditioned for The X Factor and was put into the girl group Fifth Harmony.

Shawn Mendes

Before he was one of the biggest recording artists in the world, he boyfriend, Shawn Mendes, was once a normal kid too — and boy, did he look different back then! We’re especially loving the braces.

Selena Gomez

We almost didn’t recognize Selena Gomez in her yearbook pic! As fans know, the former Disney star actually starred in a few things as a kid (most famously, she appeared in an episode of Barney), so she’s been in the spotlight since she was little. But that didn’t stop her from attending school!

Justin Bieber

Miley Cyrus

OK, some stars have changed a lot over the years, but we think Miley Cyrus still looks the same, TBH. When the Hannah Montana star took this yearbook photo, we bet she had no idea that she would one day become a super famous actress and singer!

Demi Lovato

Awww — Demi Lovato was so cute as a kid! She may have grown up over the years and totally transformed, but she still has the exact same smile.

Zac Efron

This is what Zac Efron looked like before his High School Musical days! That’s right, long before the Disney star was cast as Troy Bolton, he was a real student, and it’s said that it was his drama teacher that pushed him to get into acting!

Joe Jonas

Joe Jonas

Joe Jonas, is that you?! Yep, he was a pretty adorable kid, and we totally see the resemblance!

Liam Hemsworth
