J.K. Rowling turns 54 today.

Throughout the morning, a huge number of fans took to social media to send her happy birthday wishes.

Emma Watson was among them. The Harry Potter star hit Twitter and Instagram to share an undeniably wonderful photo of herself, Rowling, and former co-star Evanna Lynch in their best fancy dress getup.

It's not clear exactly where that photo was taken, but Watson shared a photo of herself in that same Wonder Woman outfit back in September 2018 -- so it could have been snapped during an early Halloween party.

Either way, Lynch, known for playing Luna Lovegood in the Harry Potter movies, certainly approved.

Rowling hasn't responded yet, but she hasn't been personally active on social media since fan backlash over comments she made about Dumbledore that were made public in March.
