Katy Perry interviewed for March cover of Glamour

Famed Instagram post Cleo Wade interviewed her friend Katy Perry for Glamour.

-Shows are different physically now that she's older and she can't do them hung-over or after eating whatever she wants. She has a chef who does a no-sugar and no-dairy diet for her which helps.

-Says people on Idol come in with personal stories, but if they actually can't sing, the backstory has to come second and she hopes she doesn't get turned into "that bitch" because of it.

-Is preparing for a major "soul surgery" to "emotionally elevate' herself this year because she wants to be prepared to start a family and she doesn't want to transfer her lingering feelings from her childhood traumas to her children.

-Last year's focus on killing her ego was really necessary for her career.

I didn’t realize how much I relied on the outside validation. I thought that I didn’t, but once you get kicked down the mountain a little bit, you realize that the weather really is better at the top. It’s been really necessary for me to go through that. [And I’ve learned that] people don’t relate to someone who is perfect or always winning anyway. You can’t always be sitting perched on top of the mountain.
