Puberty doesn’t always have to be your enemy.

It’s been a well-known fact for a while now that Neville Longbottom, aka Harry Potter actor Matthew Lewis, grew up and got insanely attractive. He grew into his teeth, he got a great hair cut and he ditched his awkward Neville personality.

In case you’ve forgotten, this was his transformation:

Neville as a HP dweeb on the left. Neville now. Swoooon.

With that, he started a movement known as “Neville Longbottoming” – it’s where former non-heart-throbs turn into very attractive people with some time or puberty or maybe some dental work.

And there are a lot of them. Here are 10 celebrities who have Nevilled Longbottomed. Hard.

1. Calvin Harris.

The DJ/new boyfriend of Taylor Swift was once an awkward Scottish dude with black hair. He decided to turn it blonde, get a tan and moonlight as an underwear model.

Check it out.

8. Nick Jonas.

He was a Disney star who sang with his brothers and wore a promise ring. Now he sings about being a possessive boyfriend and has hair on his chest. I’m not even ashamed to say it: Nick Jonas Neville Longbottomed so hard.

9. Johnathan Taylor-Thomas.

You know him from Home Improvement, and we doubt you’ve ever forgotten his ridiculously cute face. He’s now 33 and is still cute. Just, more appropriately so.
