Nuns, priests and others Catholics in Rome joined in the "Happy" groove.

The Vatican posted  a YouTube video with Pharrell William's song titled the "Happy for 2PapiSanti."

On April 27, Pope Francis will declare Juan Pablo II and Juan XXIII saints. The Vatican plans to live stream the canonization ceremony to be held at St. Peter's Square.

The church's social media marketing effort is using hash tags "#2PapiSanti" and "#2PopeSaints."
