Fans will get to see everything when her concert documentary, Katy Perry: Part of Me, hits theaters on July 5, but in the meantime, Katy dishes about some of her toughest days on tour and about still believing in love in the latest issue of The Hollywood Reporter.

"There were times when what was going on in my personal life was so overwhelming that I had to bend over to let those tears fall straight out of my eyes and not my false lashes just as I'm about to go up that ramp and sing "Teenage Dream," Katy told THR of what was going on behind the curtains of her tour. Her breakup with Russell was HUGE and publicized. Katy spoke of the her divorce, saying, ""Like how I write my songs, honesty has always worked for me. So if it ain't broke, why f--ing fix it?" Adding that much like Kim Kardashian and Kris Humphries divorce, "Nobody knows what really happened except the two people who are in it." And despite everything that's happened, Katy says, "I still believe in love!"

Katy also dishes on how her parents are being misrepresented by the media and how her father's comments "were taken out of context," saying, "There's not a whole you can do. You hope that it passes, which it always does, but they have to be careful. They didn't necessarily sign up for this." And about shelling out $2 million of her own moola to fund Katy Perry: Part of Me. "Trust me, I have a vision. My frugal business manager, God bless him, was sweating."

It's been a very busy couple of years for Katy and she isn't about to slow down now. The Firework singer is planning to launch her own record label. Katy told THR, "When it does come to fruition, I'm going to try and avoid the things that take away any fighting chance for an artist to have financial success."

Such a strong, amazing performer to go on with the show.... Don't you think?
