List Rules Vote up the most surprising transformations.

Puberty is a rough time for everyone. Thankfully, most people emerge on the other side pretty much unscathed and more or less intact. But for some, puberty is a major transformative process that turns ugly ducklings into swans. This is certainly the case for nerdy child actors who grew up to be hot adults.

There's a temptation to pass these transformations off as merely the byproducts of being a celebrity. After all, these onetime child actors had lucrative careers, and they could likely afford all the personal trainers, nutritionists, chefs, stylists, and makeup artists money could buy. But that explanation is too dismissive. With changes as major as the ones on display here, there had to be some amount of work and dedication involved – and at least a little bit of personal reflection and awakening.

Though the public is used to hearing stories about great child stars struggling or falling on hard times, these stories prove that the opposite can also be true. These are instances when puberty helped child actors instead of hurting them, and buoyed them instead of sinking their prospects for a happy, successful life. Look at these nerdy child actors then and now, and judge their transformations for yourself.

As Neville Longbottom in the Harry Potter films, Matthew Lewis was a plump, chubby-cheeked kid whose signature role was far from glamorous. Neville was awkward and ungainly and more than a little disorganized. But as the series evolved, the character did too, and Neville ended up being a fan favorite.

Lewis became a fan favorite in real life as well, thanks in part to his jaw-dropping emergence into hotness. In 2015, Lewis did a spread in Attitude magazine, revealing a surprisingly ripped body. Even Neville's creator, J. K. Rowling, gave her approval. "I will always support you whatever you want to do, Matthew," she tweeted. "Now go put some clothes on."

The transformation, or at least part of it, was purposeful; Peck has discussed his weight loss and his desire to take control of his health.

Peck continues to act, and has been discovered by a new generation via his YouTube, Snapchat, and Vine videos.

Looking at him today, it's hard to believe Jerry O'Connell ever had an awkward phase. But there was a time when O'Connell wouldn't have seemed destined for sexiest men lists. His big-screen debut was as Vern Tessio, the pudgy, shy member of the group. After a few years and a lot of trips to the gym, he emerged victorious over puberty... and hot.

O'Connell, who is married to the equally hot Rebecca Romijn, also has the distinction of making eyebrows sexy. Just look at them!

Age: 43

Birthplace: New York City, New York, United States of America

Credits: Stand by Me, Sliders, Jerry Maguire, My Secret Identity

You probably know Daniel Curtis Lee as cyber-geek Simon "Cookie" Nelson-Cook on Nickelodeon's Ned's Declassified School Survival Guide. He was just 13 years old on the show, a tough age for anyone, but especially for someone going through puberty in front of the whole world. It probably didn't help that Cookie was your textbook nerd, complete with thick glasses and braces.

Lee's puberty and adolescence are long behind him now, and he possesses a GQ level of hotness. In addition to acting, Lee is a comedian, musician, and rapper, but he could easily be a model.

Age: 25
