Our gal Saoirse is back and, as usual, she's dropping her Irish charm all over the place.
The Dublin native visited The Tonight Show on Tuesday night and treated us all a sing-song of an Irish classic - Fairytale of New York - and nailed it.
Originally sung by The Pogues and Kirstie Mccall, the pair delivered, and managed not to butcher the most listened to Christmas song in Ireland as they drank a pint of the black stuff in between lines:
The actress didn't visit Jimmy just to have a sing-along. Promoting her latest movie Mary Queen of Scots, in which she plays historic figure Mary Queen of Scots alongside Margot Robbie, Fallon surprised Ronan with a question from her co-star.
A Saoirse Ronan heavy episode, the actress went on to answer questions about her favourite movie Bridesmaids and turned into Monica from Friends during a game of charades.
Mary Queen of Scots is released January 18, 2019.
