Katy Perry talks some more about Miley.

"She knows exactly what she's doing. I think a lot of pop girls who come from a bit of a controlled (thing) -- Nickelodeon or whatever it is -- they always feel the need that they've got to shed their skin, and bloom again, and butterfly, or peacock, or whatever. I love her. And I think she's hot. I like what she's doing. She's a smart little cookie."
