Saoirse Ronan appeared on The Late Show with Stephen Colbert on Tuesday and during the charmingly hilarious interview she gave Stephen a few tips on how to perfect his Irish accent. Once he had ‘mastered’ the accent, Saoirse helped Stephen pronounce some tricky Irish names, such as Tadgh, Siobhan and, most baffling of all, Caoimhe, which had Stephen joking “you go to hell!” at his Irish accent mentor.
