In the latest issue of Marie Claire, the 29-year-old singer says she banned mom Mary Hudson and dad Keith Hudson (both pastors) from the big celebration back in January (seriously!).
"People don't understand that I have a great relationship with my parents—like, how that can exist," Perry tells the mag of her super religious parents. "There isn't any judgment. They don't necessarily agree with everything I do, but I don't necessarily agree with everything they do. They're at peace with—they pray for me is what they do. They're fascinated with the idea that they created someone who has this much attention on her."
"My parents are Republicans, and I'm not," she continued. "They didn't vote for Obama, but when I was asked to sing at the inauguration, they were like, 'We can come.' And I was like, 'No, you can't. I love you so much, but that—on principle.' They understood, but I was like, 'How dare you?' in a way."
When asked about her current religious views, the "Unconditionally" singer revealed, "I don't believe in a heaven or a hell or an old man sitting on a throne. I believe in a higher power bigger than me because that keeps me accountable. Accountability is rare to find, especially with people like myself, because nobody wants to tell you something you don't want to hear. I actually don't trust people who start to turn on me because they get scared of telling me the truth. I'm not Buddhist, I'm not Hindu, I'm not Christian, but I still feel like I have a deep connection with God. I pray all the time—for self-control, for humility. There's a lot of gratitude in it. Just saying 'Thank you' sometimes is better than asking for things."
As for her transition from a former gospel singer into a sexy and provocative pop star trying to make it in Hollywood at the young age of 17, Perry said, "It built a lot of character, having to earn all of it over and over. Once you have it, you're so appreciative."
