Offaly man Sean McLoughlin, better known by his online moniker, Jacksepticeye, was the big star on RTE's Late Late Show.
The Cloghan native has amassed over 18 million YouTube subscribers in five years and some of his fans were invited onto the show to catch a glimpse of him away from the screen.
One such fan was Jane Anne O'Sullivan who was invited to ask a question, but was so overwhelmed by meeting her idol, she burst into tears in the audience.
Host Ryan Tubridy and Sean then stood up and went to her, inviting the young Cork girl onto the stage to ask her question. Jacksepticeye then held her hand and offered her advice on being herself and taking every day as it comes when she feels overwhelmed.
Sean spoke of his YouTube fame, an activity that started as a hobby but has since turned into a career making the Offaly man a millionaire, although he was coy on the amount of money he has made.
