Katy Perry, Darren Criss, Selena Gomez and more come out for KIISS-FM'S Jingle Ball

katy-performing.jpg KIISS FM's Jingle Ball concert go-ers got to unwrap their very own present a few days early on Sunday, Dec. 5: Katy Perry. The singer was just one of the many performers ( B.o.B., Hayley Williams, Selena Gomez to name a few) at the event, but Perry brought the holiday spirit with her as fake snow came down on the stage that was filled with snowmen, presents and elves. Celebrities like "Glee's" new fan favorite Darren Criss, Victoria Justice, Joel McHale and more came out to enjoy the concert.
