Katy Perry: Why I Included The Breakdown Of My Marriage In New Documentary

June 22 2012, Published 6:00 a.m. ET

Katy Perry, appearing on The Tonight Show Jay Leno Thursday night, says she left the lowlights of her failed marriage to comic Russell Brand in her new release Katy Perry: Part of Me, to preserve the integrity of the 3D documentary.

"Just because you're in the spotlight doesn’t mean you get to dodge the curveballs -- they're actually bigger," the Wide Awake singer told Leno. "I think if you were to see the movie and it was completely avoided, you'd think, 'Hmm that's strange, I know something else happened in her life last year.'"

Katy said she wanted to handle the split "delicately with the most integrity I could, and show, 'Yeah I'm going through the same situation that half of America goes through and somehow I landed on my feet.'

"So you don't have to lay down and die like you think."

The Firework singer added that "it wasn't always exciting to watch those unflattering scenes where I'm crying and having an intense moment, but I think people will relate to me more seeing me at my lowest point and now at my highest point."
