During her London concert this week, Katy Perry got to hang out backstage with one very special fan: Adele! The “Dark Horse” crooner and the “Someone Like You” singer got to enjoy and little meet and greet and even posed for a selfie together. In the super-cute pic, which Perry posted on Instagram, Adele poses behind Perry in the concert dressing room. Both stars look gorgeous and camera-ready. Perry is currently on her Prismatic World Tour. After her London shows, Perry will take a mini-break before making her way around the U.S. for several dozen shows.
