Elon Musk shows off photo after meeting Pope Francis

Elon Musk shared a photo on Twitter of himself with Pope

Francis, after 10 days without activity on the social network.

The tycoon is seen in the photo next to the smiling Pontiff, along with four of his seven children.

"It was an honour to meet @pontifex yesterday," Musk tweeted.

Pope Francis and Elon Musk held a meeting, lasting around 40 minutes,

on Friday afternoon at Casa Santa Marta.

The meeting, which was private in nature, was not on the official agenda of the Argentine pontiff.

Neither the Tesla CEO nor the Vatican have given details about the topics that were discussed during the meeting.

The head of the catholic church has nine Twitter accounts, in nine languages, and almost 53 million followers.
