One Direction are the biggest pop phenomenon in history. In When Ryan Met Niall, Ryan Tubridy goes to Mullingar to talk to some of the people who helped make Niall Horan the man he is today. Ryan then catches up with him during the middle of One Direction’s sold out stadium tour of America for a back stage chat which covers everything from hanging out in London with President Michael D. Higgins to what he thinks of Ryan’s Christmas jumpers.
