Katy Perry has been celebrating her return to the real world by once again inviting fans onstage during her shows. For her latest Prismatic World Tour set at Rock in Rio, the singer invited this uninhibited gem, Rayane, onstage for hugs (?), a Portuguese lesson, and a selfie. Things got kind of weird because some sort of substance may or may not have been involved. (Un)fortunately, there was no Segway.
