In her Instagram stories, she said: ‘Happy Saturday everyone, I’m here in Rome at the Vatican, to speak on meditation. I’m with my momma, my darling [Orlando], and my manager, Steve! It’s a great day! I am so excited!’

The singer was brought up by devoutly Christian parents, Keith and Mary Hudson. Last year she discussed their feeling towards her music during an interview on Smallzy’s Surgery radio show. ‘The thing about it is, which is such a weird thing, to really understand we agree to disagree but still with loving space,’ she said.
‘We all come from different places… you can have your belief system, nobody is telling you to not believe your beliefs but you can also come from a space of love.
She added: ‘That’s what my family and I exercise all the time.’
Among other songs that raised eyebrows in the Perry family, her 2008 hit I Kissed A Girl was also cause for concern.
