It's a rare thing to look on YouTube, go against your better judgment and scroll through the comments on any story and see nothing but positivity.

Irish actor and singer Jessie Buckley, who made a stir with her lauded role in 'Wild Rose', is currently in America promoting the film and appeared on Colbert performing a flawless version of 'Glasgow'.

She also sat down with the famous host for a chat and was typically charming.

She has work in-coming in big-budget Robert Downey Jr. flick 'The Voyage of Dr. Dolittle' and a big role in Charlie Kaufman's next film, 'I'm Thinking of Ending Things.'
