The wedding took place in Castletown Geoghegan
A Westmeath couple had an uninvited guest pop up at the alter during their Wedding ceremony.
The pair were getting married in Castletown Geoghegan, when a mouse scurried down the steps towards the congregation as the priest continued the mass while the bride and groom tried to contain their laughter.
Everyone remained calm as the rodent made it's way toward the cameraman.
A video, captured by the couple's photographer, Fra Lucchesi, went viral on Instagram.
Mr Lucchesi says the clip has been watched over half a million times so far:
