Appearing on The Ellen DeGeneres Show, the 'Wide Awake' singer insisted that she wanted to give fans an honest portrayal of her life in the project, including the more difficult times as they have been an important part of her journey.
"I thought it was important to show everything in between. I think sometimes people think that we're perfect, and we know we're not perfect, at all," Perry explained.
"I think it's important to start breaking down the idea that to achieve your dreams, you always have to be perfect or flawless or live in some kind of fantasy world. So that's why I decided to put everything into the film. In the most tasteful way.
"But mostly it's about how I got there and the ride along the way, which can be bumpy. But mostly, it was extremely fun."
The 27-year -old, who will release Part of Me on July 5, recently revealed that the project was inspired by Madonna's 'Truth or Dare'.
Earlier this week, it was announced that Perry had split from Florence + the Machine guitarist Robert Ackroyd, who she dated for a little over one month.
