On hubby Russell Brand, Katy says, “I always knew I wanted a great man of God, someone who was going to be an inspiration for people and also be a lovely husband and father. We’re at different places in our lives, but we can still grow together. He’s thought-provoking, articulate, a real advocate. I also definitely wanted to have a laugh. I have all that in him.”

When asked about her image, Katy says, “I’m kind of a good girl - and I’m not. I’m a good girl because I really believe in love, integrity, and respect. I’m a bad girl because I like to tease. I know that I have sex appeal in my deck of cards. But I like to get people thinking. That’s what the stories in my music do.”

So what about her famous BFFs like Rihanna? “We’re all unique. That’s why we all win and we all can exist. People don’t want just vanilla. They want 31 flavors. I couldn’t do what Rihanna does. I couldn’t do what Gaga does. They can’t do what I do.”
