Hummer: Katy Perry

"We nailed it: It's roller-skating! It's '90s! It's Ace of Base! It's Cyndi Lauper! It's like all these colors and more. There might be some really cool guest appearances by some cool rappers from the West Coast. I mean, you'll just have to see, since I'm a California girl, you know. And then some best friends might be appearing. ... We'll see! It's going to be fun. It's going to be one of those records that is everybody's favorite guilty pleasure."

-- Katy Perry discussing her soon-to-be released sophomore album.
