Katy Perry doesn't believe in heaven and hell. That's probably as a result of being brought up in a deeply Christian household with evangelist preacher parents. All is not lost though, Keith and Mary, she does believe in a "higher power". That's a start.

In an interview with US Marie Claire magazine she said: "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'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 it happens, she has a "great relationship" with her minister parents, despite their conservative values often being at odds with her pop career, which involves wearing spinning udder bras and marrying the likes of Russell Brand (who was totally trying to impregnate her the whole time).

She added: "People don't understand that I have a great relationship with my parents... like, how that can exist. There isn't any judgement. They don't necessarily agree with everything I do, but I don't necessarily agree with everything they do. They're at peace... 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."
