Katy Perry just gave a Billboard Interview to promote her new album, PRISM, coming out soon!
Katy Perry is in training for her dynamic stage shows, as she talks about during the Billboard interview: "I am exhausting so much energy right now.  For eight days straight, I've been conditioning -- just going, going, going at the height of my physical capabilities. I'm supposed to eat meals every two hours, but it takes me an hour to think of what I want to eat, so by lunchtime, I'm starving. I'm just so hungry all the time."
Katy Perry talks about past mistakes in giving interviews during her Billboard interview: "I shouldn't have done the interview: I was playing Madison Square Garden that same night, and I knew that the end of my marriage was coming. I was just exhausted and stressed," Perry says. "I'd prepped everyone that I was running late, but Barbara showed up at the original time anyway. When I got there, I apologized immediately, but then she said to me, 'You know, I've only ever waited for one other person this long, and you know who that person was? Judy Garland. You know how she turned out, right?' I was like, 'Oh, snap! Yes, bitch!' I think it's the coolest thing that Barbara Walters shaded me. I just couldn't tell her as we were sitting down for a mega-interview, 'Hey, my marriage is falling apart. Give me a break.'"

Katy Perry talks about the process to decide the release date for her new album PRISM in the Billboard interview: "In May, I sat down with my managers and said, 'Guys, I think I'm going to have everything ready enough to come out this fourth quarter,'" Perry says. "We weren't really thinking we'd be able to put anything out until February, but you don't want to sit on something that's about to burst."

Katy Perry talks about how personal all of her songs are during the Billboard interview: "All the songs are real-life moments. I can only write autobiographically. I put all the evidence in the music. I tell my fans if they want to know the real truth about stuff, just listen to the songs."

Katy Perry also dishes about her boyfriend John Mayer during the Billboard interview: "I can't believe I'm wearing my boyfriend's shirt!  He literally is a genius, as is evident from his songwriting. I always tell him, 'Darling, you know I'm going to have to give your mind to science after you've passed, because we're going to have to understand how all these sparks work.' We'll be in bed, and he'll be doing the crossword puzzle. Every night, he tries to finish it in under 10 minutes. When he puts his mind to something, he really gets it done very well. I always ask for his help."

Katy Perry talks about how she sees her career evolving during the Bilboard interview: "I love Madonna to death, but she's never going to give me that damn baton," Perry jokes. "I'll probably turn into more of a Joni Mitchell. As I inch towards my 30s, I think my fourth record will be more of an acoustic guitar album. That's where I started when I was first discovered by Glen Ballard and got my first record deal. We'll see-I can't get ahead of myself. I'm still doing the work: I'm a good balance of left and right brain, and to be an artist with a long career, you've got to have both. One thing John said to me was, 'It's harder maintaining success than finding it.' I've got a few records under my belt, and I still feel like a brand-new artist. People still want that truth to cut through."
