The pop queen's new album, "PRISM," was shaping up to be darker than anything she'd made before. Then she looked inward and changed course. The result is the most spiritual album she's made yet, led by her eighth No. 1 on the Hot 100, "Roar."
"Honestly, I'm just masquerading as a pop star." Coming from Katy Perry -- that most DayGlo of pop stars -- such a statement could verge on the absurd. But today, Perry has stepped outside the smoke and mirror balls.
