Last night, Jessica Williams stopped by The Late Show to promote her upcoming Netflix movie, The Incredible Jessica James, and told Stephen Colbert a charming story about meeting J.K. Rowling, first via Twitter and then in real life. Turns out they share a birthday and they both play the Sims for fun.

Rowling followed her and Williams promptly got “Twitter shy” until the Harry Potter author reached out with a DM to inform her that she’d meant to wish Williams well on their shared birthday but “bloody forgot, which is typical me.” Williams took a week to craft her response, but she now refers to her new buddy as “JoJo” and shared a picture of them together, barefoot. Now that’s what I’d do with my time were I as wealthy as Rowling.
