Perry got very emotional during a tear-filled therapy session for Viceland's show "The Therapist" with Siri Sat Nam Singh.
"I feel ashamed that I would have those thoughts, feel that low and that depressed".
Katy Perry also brought in meditation teacher Bob Roth, whom she met through ex-husband Russell Brand.
Perry protested vehemently at first: "They're all incredible lovers and I would have sex with all of them after I get out of this place!" she told Corden.
We are left in awe of Katy's courageous honesty, and love her even more for keeping it so real.
She continued, "I don't know". It's an album filled with songs that Perry connects to personally, including one that's made headlines - "Swish, Swish", a track rumored to be about her long-running feud with Taylor Swift. And I didn't know that I did it wrong until I heard people saying I did it wrong.
In 2013, Perry had drawn an angel card (a Tarot-like deck that "guides the recipient toward their best life") with the word "authenticity" written on it.
"And I just have to say, 'You are your own person, I am my own person, and my intentions are pure'". "I do the right thing any time that it feels like a fumble".
Katy Perry has ranked her famous lovers from best to worst!
She admitted that there are far bigger problems going on in the world and so, although neither of them may agree with everything the other does, she hopes that can come together "in a place of love and forgiveness and understanding and compassion". "Josh Groban is in there", she told Corden, before adding, "I'm just kidding". [But] that's the point of this whole thing, she said.
