Niall Horan has gotten together with some of his friends to remind us all to "unite by staying apart."The effort from the "Nice to Meet Ya" singer and Hozier has resulted in a rousing video in which a galaxy of Irish stars encourage us all to do our part to flatten the curve during the COVID-19 pandemic.‘The Irish are known all over the world for being passionate, fun-loving and very patriotic people,’ the video begins, with footage of Horan and Hozier at home.
