J.K. Rowling Reveals Which House Harry Potter's Son Has Been Sorted Into!

Back-to-school season isn't just for muggles! J.K. Rowling tweeted that Tuesday is James S. Potter's first day at Hogwarts. They grow so fast, don't they? This means that in two years, Harry and Ginny's younger son, Albus, will start school, too. (That's the scene we see at the end of Harry Potter and the Deathly Hallows — Part 2.) Not only did Rowling remind fans that today is the big day to go #BacktoHogwarts, but she even cutely responded to a few people. Check it out, and let your Harry Potter-loving heart swell with joy.
