Niall Horan delighted fans at his sold-out Dublin concert by bringing out Ed Sheeran for a surprise acoustic performance of One Direction's hit 'Little Things', which Sheeran wrote, and his own track 'Lego House'. The duo performed at the Royal Hospital Kilmainham, where Horan expressed his gratitude for Sheeran's presence, highlighting their friendship and Sheeran's love for Ireland. This collaboration is part of Horan's ongoing tour for his album 'The Show', which concludes in October after stops across multiple continents. Sheeran is also currently touring Europe and recently joined Taylor Swift on stage during her Eras Tour at Wembley. Both performances evoke nostalgia as they revive popular romantic ballads that once graced the Billboard Hot 100. Fans have widely acclaimed this surprise duet, which reflects the enduring popularity of both artists.
