Pop beauty Katy Perry has revealed that she wanted her brand new concert movie to be realistic and to showcase everything that goes on "under the hood".

In a new interview with Jay Leno, the 'Teenage Dream' sensation explained that although some of the things she's gone through over the past year have been incredibly painful she wanted to be true to her life's story so decided to include everything in the motion picture:

"I think that if you were to see the movie and it was completely avoided you would come out of the theatre thinking, 'Hmmm, that's strange, I know something else did happen at that time in her life last year'. So I wanted to handle it very delicately, with the most integrity I could possibly have, and show people that I'm going through some of the same situations that most of America, or half of America, goes through."

She also added that incorporating "unflattering scenes" was important to her because she wanted to make herself as relatable as possible to both her fans and to the general public:

"Somehow I landed on my feet, and you don't have to lay down and die even if you feel like you're going to. It wasn't always exciting to watch those unflattering scenes where I'm crying and having an intense moment, but I think that people will relate to the movie even more, seeing me at my lowest point and now at my highest point."

"I wanted to show people what was under the hood."
