J.K. Rowling birthday: Harry Potter author celebrates with King's Cross cake

It’s no coincidence that J.K. Rowling and Harry Potter share a birthday. The writer, who recently celebrated the opening gala performance of the Cursed Child stage production in London, commemorated 51 years of living with a special King’s Cross cake.

“I got a cake in the shape of King’s Cross at midnight,” Rowling tweeted, referring to the famed London railway station that doubles as the destination for Platform 9 3/4 in the Harry Potter series. “Thank you so much for all the birthday wishes! I’m very fond of you lot, too.”

Elsewhere, Rowling posed with Cursed Child‘s resident Hermione, Noma Dumezweni, for a photo. “Noma gives the best birthday hugs,” she wrote on Twitter. As for a not-so-pleasant surprise, the writer posted a photo of her son’s gift: a coffee mug with an owl saying, “F— off.”

“I think we can all agree that this is an unacceptable gift from a son to his mother on her birthday,” she tweeted.

Rowling attended the opening gala for Harry Potter and the Cursed Child at the Palace Theatre on Saturday.

She said on the red carpet, “I am so proud of this play. I always try to avoid the world ‘magical’ for obvious reasons, but it has been magical. I’ve loved every moment of it. It’s been a wonderful process.”
