As for why she included her break-up on camera, "You can’t avoid an elephant in the room, of course," Katy told ABC's Elizabeth Vargas in Nightline interview that previewed on Good Morning America. "But I wanted to be very diligent and respectful about it."
"Hopefully, you know, people see that problem and they see me having that problem, they’re like, 'Oh. Well, even she can’t dodge life’s curve balls. Even at that level.' And they can relate to me better," Katy continued.
Perry, who's sold 75 million records and has eight Grammy nominations and more than one billion YouTube views, has also overcome a very rocky career start. She was dropped from four record labels before signing with Capitol Music Group in 2007. By that time, she'd been performing for ten years.
"When I was 13, I asked for a guitar. And that’s how I really started explaining my point of view," Katy said . "I think at the end of it all, I will always have that to fall back on."
"It was a lesson learned. And that’s what’s most valuable," Katy explained. "People always ask me, 'What is it that you regret?' And I say, 'nothing, because I could not buy what I’ve learned.'"
Katy said she decided to turn cameras on in her pop star life after the success of her album Teenage Dream.
"I thought to myself, 'Well, I think this is going to be a moment. Maybe I should catch it on tape," Katy said. "I’m either going to go completely mental, completely bankrupt, or have the best success of my life."
Katy Perry's full interview airs on ABC News’ Nightline tonight at 11:35 p.m. ET.
