JK Rowling celebrated her 55th birthday on the same day as Harry Potter’s 40th.
In the movies the bespectacled wizard is played by Daniel Radcliffe, who is just 31 in real life.
The event’s got a lot of fans online, tweeting and re-tweeting what the Harry Potter books mean to them.
Following all the backlash she’s gotten from recent weeks over her Transphobic comments, the writer had this to say:
To all the lovely people who’ve wished me happy birthday, thank you so much and look at my surprise birthday cake! 💚💚💚 pic.twitter.com/cgkohO7Hs0
