We recently learned that Harry Potter scribe J.K. Rowling and The Incredible Jessica James star Jessica Williams are secretly best friends after Williams spilled the beans on The Late Show With Stephen Colbert.
Turns out it’s not just a casual friendship: The two share a birthday (July 31), and as Rowling tweeted Tuesday morning, they celebrated their birthday together this year, complete with cake and tiaras. (Though only Williams is wearing hers in the photo because, Rowling notes, “my tiara really pinched.”)
As Williams explained on The Late Show last week, their friendship began over Twitter in 2013, when Rowling, a fan of Williams’ work on The Daily Show, sent her a DM. They went on to exchange birthday greetings, though Williams always wanted to ask one burning question: What Hogwarts house would she be in? So she took a shot (a literal shot… of alcohol) and asked. Rowling sorted her into Gryffindor — then asked to hang out next time Williams was in London.
Check out the whole enviable story above. In the meantime, here’s hoping Rowling is brainstorming characters for Williams to play in the next Fantastic Beasts movie…
