Here is Katy Perry dropping the upskirt and her massive cleavage in Rio de Janeiro, Brazil on Monday. Katy Perry was wearing a short revealing cut-out dress to the photocall for her movie and she was nice enough to go out on the balcony to see the fans. Her fans and the paparazzi got a nice little treat… Anyway, it is interesting that even in some upskirt pictures with a direct from underneath shot up to her crotch her boobs still manage to steal the show. Enjoy! Click on pictures to enlarge.
