We guess he made quite the impression!

Katy Perry opened up about revisiting her Christian faith after a meeting with Pope Francis in the newest issue of Vogue Australia, and it sounds like her religious parents couldn't be happier.

"Now that I'm in my 30s, it's more about spirituality and heart goodness [for me]. My mom has prayed for me my entire life, hoping I'd come back to God," she confessed to the mag.

"I'm such a big fan of Pope Francis. It's a combination of compassion, humility, sternness and refusal. He is a rebel - a rebel for Jesus," she gushed.

The pop princess began her rebirth while attending a weeklong spiritual retreat at the Hoffman Institute, and she highly recommends it for anyone going through some challenges in life.

"For years, my friends would go and come back completely rejuvenated, and I wanted to go, too. I was ready to let go of anything that was holding me back from being my ultimate self. I have had bouts of situational depression and my heart was broken last year because, unknowingly, I put so much validity in the reaction of the public, and the public didn’t react in the way I had expected to … which broke my heart," she confessed.

"Music is my first love and I think it was the universe saying: ‘Okay, you speak all of this language about self-love and authenticity, but we are going to put you through another test and take away any kind of validating “blankie”. Then we’ll see how much you do truly love yourself.’ That brokenness, plus me opening up to a greater, higher power and reconnecting with divinity, gave me a wholeness I never had. It gave me a new foundation. It’s not just a material foundation: it’s a soul foundation," she added.

She's come a long way since her "I Kissed A Girl" days!
