Katy Perry fever is at an all-time high with her 3D movie, "Part Of Me," hitting theaters on July 5. The documentary follows Katy on tour, where she's sobbing backstage during the end of her relationship with Russell Brand and, just a minute later, getting a huge welcome from her fans. It seems like the film might be a bit of an emotional roller-coaster --- but if anyone can power through rough times and come out "fine, fresh, and fierce," it's Katy.
