Perry wore a totally black outfit with a matching hat while he was standing and shook hands with the head of the Catholic church. Bloom wore a suit and tie.

They also met and spoke with Bishop Paul Tighe, the Secretary of the Pontifical Council for Culture, during the event.

During the Pope's speech, they used headphones to listen to the English translation.

Perry, 33, and Bloom, 41, have reappeared intermittently in the past, but have not yet publicly confirmed that their relationship has returned . However, during an Instagram story before the event, Perry referred to Bloom as his "darling".

"I'm with my mom, my darling and my manager Steve," he said. "This is a good day!"

He also said that he was at the event to talk about meditation.
