California Gurl Katy Perry unleashes her promotional pictures for her new album, "Teenage Dream." The singer puts on her purple wig and strikes a pose for these flawless pics. Her second single shares the name of the album and is a nice mid tempo ballad that's expected to do well on radio and the charts. Time will tell but she surely is killing the competition in the current Artist Of The Month poll. "Teenage Dream" drops August 24th.
