Pattinson is currently in Northern Ireland for his new movie The Lost City of Z, in which he plays 1920s British explorer Percy Fawcet.

A wedding guest warned Pattinson he was "going to get mobbed by about 20 girls," but insists the actor was happy to stick around and pose for photos with the bridesmaids as well as the bride and groom.
