  • "Harry Potter" fans gushed over the pair on Twitter

The upcoming "Harry Potter" reunion special is getting fans excited about Emma Watson and Tom Felton all over again.

Watson, 31, and Felton, 34 — who appeared in all eight "Harry Potter" films as Hermione Granger and Draco Malfoy, respectively — reunited in a recently released sneak peek at a special that marks the 20th anniversary of "Harry Potter and the Sorcerer's Stone," which officially hit theaters Nov. 16, 2001.

The pair ran in for a hug with big grins on their faces when they reunited on-camera in Hogwarts' Great Hall for the HBO Max special.

In the trailer, the "Beauty and the Beast" actress also recalled her crush on Felton and how he made her heart skip a beat for the first time when they were filming the "Harry Potter" movies.

Watson admitted that she "fell in love" with Felton during a tutoring session, where they were asked to draw what they thought God looked like and the then-young actor "had drawn a girl with a backward cap on a skateboard."

"Harry Potter" fans immediately took to Twitter to express how much they adore this pairing.

"I have literally been obsessing over Tom Felton and Emma Watson ever since the reunion trailer came out, and I am not sorry AT ALL," one tweeted.

"Can Tom Felton and Emma Watson get married?" another user wrote.

"They are so perfect together I cannot," a different netizen agreed.

"Emma Watson and Tom Felton hugging is precious," one fan wrote, while another said, "When Emma Watson is so shocked when she saw Tom Felton and Tom looked so happy seeing Emma [plus] the way they hug each other aaaaah! I've been waiting for this so long and it's worth it."

While recalling her crush on her co-star in the reunion special's trailer, Watson revealed that it would be "an extra exciting day" for her on set whenever she came in and saw Felton's name on the call sheet. "He was three years above me and so for him, he was like, 'You're like my little sister,'" she shared.

While the two never dated, Felton said he was fully aware of his secret admirer. The actor recalled being told, "Yeah, she had a crush on you," once when he was in the hair and make-up chair.

"I became very protective over her. Yeah, I’ve always had a soft spot for her and that continues to this day," Felton added.

Watson said that nothing "ever, ever, ever" happened between them in a romantic sense, but they have remained friends since the film series came to an end in 2011.

Felton previously addressed the dating rumors in June after being asked about a possible romance between him and his former co-star.

"We are something, if that makes any sense. We've been very close for a long time. I adore her," he told Entertainment Tonight at the time. "As far as the romantic side of it, I think that's a Slytherin/Gryffindor thing rather than a Tom and Emma thing. I absolutely think the world of her."

"Harry Potter 20th Anniversary: Return to Hogwarts," which also features Daniel Radcliffe, Rupert Grint, Helena Bonham Carter, Gary Oldman and Ralph Fiennes, will be available to stream on HBO Max starting Saturday.
