Celebrity Yearbook Photos

If this star looks familiar, it might be because she got her big break playing a high schooler! Even way back when, she had a gorgeous smile to match her beautiful singing voice.

This singer was just as handsome in high school as he is now! Back then he was honing his talents at a performing arts school. Little did he know he was about to hit it big as part of one of the biggest boy bands of the '90s!

Even with a gap-toothed grin, this cutie exudes a ton of charm! We're not surprised -- he grew up to be a charismatic performer.

Check out that adorable smile! Even at a young age, this superstar looked ready to belt out a Top 40 hit.

This pop star has always been a charmer -- even way back when! If you need proof, just take a look at his yearbook photo.

This fashion-forward star was a total cutie as a kid. Just look at that adorable smile and awesome hair!

This cutie first charmed audiences when he was an adolescent Mouseketeer, but these days you can catch him collaborating with some of music's biggest names.

This father-to-be's career is a family affair, but even when he was a youngin' he was close with his brothers!

Long before this beauty was producing hit after hit, she was showing off her dazzling smile in childhood photos.

We definitely think she's the only girl in the world who can make a song about an umbrella sound catchy...

Before he earned the nickname "King of Latin Pop," this heartthrob was smoldering in adolescent photos. Even back in the day, this singer had dreamy brown eyes and his signature mole.
