Katy Perry was on Saturday Night Live land took on the guest entertainer spot. In addition to being on a skit, she took to the stage to perform in a candy land atmosphere. Singing her heart out, she performed her single, 'Teenage Dream' from the album from the same name. Her performances tonight were over the top and it is obvious that all her touring helped refine her performance and it wasn't the same as seen on the morning show weeks ago.
