Heavily pregnant Katy Perry is about to pop any time, but she has another "baby" on the way in the form of her sixth studio album, which will drop on Aug 28.

While a Katy Perry album is typically chock full of bright and shiny pop tunes, she revealed that her latest, Smile, was borne of a particularly dark time in her life.
