Potterheads rejoice. Emma Watson posted a throwback photo on social media today to celebrate author J.K. Rowling's 54th birthday.
The writer shares her birthday with the main character of her best-selling creation, Harry Potter, who would be 39 today.
Watson, who played Hermione Granger in the movie series from 2001-2011, shared a photo of her dressed as comic book character Wonder Woman, alongside J.K. Rowling and cast-mate Evanna Lynch — known for playing the character Luna Lovegood.
The actress captioned the photo with: “Sexy and scary! You smashed this. All the love to you @jk_rowling. Happy Birthday!!!! Extra points to @Evy_Lynch for being the most perfect cat."
#HappyBirthdayHarryPotter trended on Twitter, with fans paying tribute to the books.
All On The Board, known for their creative London Underground boards, gave every London underground station a magical twist by renaming the stations. Stations included Dobby Hill, Azkabank and Severus Sisters.
In celebration of the day, the Baftas shared a throwback video to when Emma Watson, Rupert Grint, producer David Heyman and J.K. Rowling picked up the Outstanding British Contribution to cinema in 2011.
Fans also added their own tributes.
“Happy birthday to Harry James Potter, one of the most kind, brave and strong fictional characters I've ever known. So incredibly thankful for all the important lessons he taught me when I was little. I'll love him and his sassiness forever," one fan wrote.
It's not just humans or muggles who got in the magical spirit, Jamee Jenkins, from Salt Lake City, shared a photo of his scottie dog, Angus, wearing a Gryffindor scarf.
“Thank you to J.K. Rowling who created this wonderful wizarding world," he wrote.
The first novel in the series about the boy wizard, Harry Potter And The Philosopher's Stone, was published in 1997. Eight movies were adapted from Rowling's seven books, starring Daniel Radcliffe in the title role.
