One particular Harry Potter star has recently made the headlines again after fans deemed him "unrecognizable" after his dramatic weight loss.

The magical world of Harry Potter gave us all our first crushes.

Whether you were into heroes or bad boys, there's no denying that Harry Potter had a whole range of heartthrobs to crush on throughout our teen years.

And even to this day, some people just can't seem to get over their obsession.

I know I can't.

It only takes one reminder...

You might just decide to re-watch the series, or you're just scrolling through Instagram and you see one of the actors living their normal, non-magical lives and find that all the old feelings start coming back...

No matter whether you had a "Harry" crush...

I mean, Harry Potter had everyone's hearts. A humble guy with the power to save the world? We stan.

And what about Hermione?

Our first-ever girl-crush and, even today, Emma Watson reigns supreme.

Or maybe you were crushing hard on Ron?

Ron Weasley was such an underrated guy, but when your best friends with people like Harry and Hermione, you're bound to be considered a diamond in the rough.

We can't forget about Ron's twin brothers, Fred and George.

No one could resist their charms.

But maybe you were more of a Cedric Diggory kind of girl?

The perfect Hogwarts student with a dashing smile... But a very unfortunate ending. Yikes.

Some of the edgier fans were head over heels for the older characters...

Remus Lupin, Severus Snape, Sirius Black and Lucius Malfoy. I mean, it's an interesting choice, but let's stick to the others, please.

There's one guy we all had a massive crush on...

And that's Draco Malfoy.

Slytherin's platinum blonde mommy's boy.

As pathetic as he was sometimes, we pitied him for the immense amount of pressure he got from his family to be the "perfect" evil son, even if he didn't want to be.

But as he got older, he started become more attractive.

The black suit? The turtle neck? The parted hair? It was a look. No one could ever pull it off as well as he did.

And that's just a fact.

So it's no wonder why no one ever got over their crush on the wannabe bad boy.

And of course, we have Neville Longbottom, who dramatically glowed up by the final movie.

Sweet, sensitive, and slightly traumatized.

But one guy that might have aged even better has been deemed "unrecognizable" by his fans.

After his dramatic weight loss, he took on some new roles on the big screen that left people questioning who this actor was.

And we even had to do a double-check just to make sure...

But it's actually him.

Upon finding out exactly who he was, people just couldn't help but comment on how different he looked.

For those of you who still have no clue who we're talking about...

Get ready for the big revelation.

It's Dudley Dursley, AKA Harry Melling.

The British actor has been broadening his horizons with newer projects including The Devil All The Time, and Queen Gambit.

Look at how much he's glowed up.

Melling told People this: "I think it was an unconscious thing when it started to happen. I went to drama school when I was 18 and that’s kind of where the weight shifted, not for any sort of major need on my side, but it’s just something that just happened."

He continued:

"And I’ve done a lot since drama school, went to do lots of theaters. I think one of the blessings of that sort of stage in my life was the fact that I didn’t get recognized."

He added:

"I had this history of being part of the films, but also I felt like I had the opportunity to sort of cause a new start, which I think is useful." But we're totally here for his new look. If you want to see more amazing transformations, then keep scrolling...
