Saoirse Ronan and Jimmy Fallon got into the festive spirit by having a little sing-song on Tuesday’s “Tonight Show”.
Ronan, 24, and Fallon, 44, went all out for the holiday season, with them donning colourful scarves and belting out The Pogues’ “Fairytale of New York”.
Fallon asked Ronan if they could have a traditional Irish pub lock-in, to which the actress obviously agreed. The duo even got the audience involved and swigged on pints of Guinness.

Ronan’s appearance also saw her reveal just how much of a “Bridesmaids” fan she is by taking Fallon’s quiz.
She then chatted about her role in “Mary Queen of Scots”, as well as taking part in a game of charades with Alessia Cara and Anderson .Paak.
