Emma Watson reunited with Harry Potter author J.K. Rowling at a Lumos fund-raising event on Saturday night. The event, which was hosted by J.K., was held at the Warner Bros. Harry Potter Tour in London and also brought out Hugh Grant, Alan Rickman, and Stella McCartney and husband Alasdhair Willis. Emma obviously has a longtime relationship with J.K., as she played Hermione Granger in all eight film adaptations of the famous book series. The actress seemed excited to be back at the enchanted studio where the movies were produced — she shared a funny photo of herself on Twitter while posing in front of a model of Hermione, saying, "Still got it. #HarryPotterWorld #watford."

Emma is likely enjoying a nice break from work responsibilities now that her latest project, the fantasy film Noah, is in postproduction. After the holidays, Emma will be back on the set to begin shooting the big-screen adaptation of Emma Forrest's moving memoir, Your Voice in My Head. The actress will play the author as a young, bipolar English writer living in New York.
