Emma Watson admitted she had a 'terrible crush' on Harry Potter co-star during filming

Emma Watson has admitted to once having a 'terrible crush' on her Harry Potter co-star during the early days of filming.

The Hermione actor, 34, took to The Jonathan Ross Show in 2012 to confess her two-year-long crush on her co-star.

Here's what she had to say:

During the interview, Watson said that she initially found it really difficult to play someone other than Hermione after the film franchise ended.

It's hard to believe that the Harry Potter and the Deathly Hallows – Part 2 came out so long ago in 2011 and it would be the last time she would play the Hogwarts student.

"I didn’t know if I believed in myself yet as an actress, outside the role of Hermione, which I knew I could do, and I did for a long time," she said.

"I didn’t know if I had other people in me or not.

"I did doubt myself a little bit.

"I think I’d just played one person, who in many ways was similar to my own personality, and I played her for ten years and I got so comfortable doing that, that the idea of coming out and playing somebody else was terrifying."

While sat on the couch, the actor recalled the first time she stepped onto a Harry Potter set.

Watson admitted that she proper fancied Draco Malfoy actor Tom Felton.

"Between the ages of ten and twelve I had a really terrible crush on Tom Felton," Watson said.

"To the extent that I would go into work in the morning and look down the numbers on the call sheet to see if he was going to be in.

"We love a bad guy, he was a few years older and he had a skateboard - and that just did it really.

"He totally knew [she had a crush on him] and the thing is that he’d tell everyone, ‘I see her in a younger, sisterly way,’ and it just broke my heart. It still does."

Well, after the release of his memoir Beyond the Wand: The Magic and Mayhem of Growing Up a Wizard in 2022, Felton said he still had a great relationship with Watson.

"I was encouraged by a few people, Emma Watson specifically, to tell the whole story and not just sort of cherry-pick the fluffy bits," he admitted.

“Not just because it was cathartic for me.

“But also in the hope that sharing those parts of my story will help others that are maybe not going through the best time.”

All's well that ends well.
