Ed Sheeran Joins Niall Horan On Stage In Dublin For Surprise Duets 'Little Things' & 'Lego House'

With the help of surprise guest Ed Sheeran, Niall Horan took fans back to the early 2010s at his concert in Dublin on Friday (August 23).

In clips captured by ecstatic onlookers at Royal Hospital Kilmainham, the two musicians strum acoustic guitars while harmonizing on One Direction's 'Little Things' – which the 'Shape of You' artist wrote for Horan's former band in 2012 – as well as to Sheeran's 2011 hit “Lego House.” “You'll never love yourself half as much as I love you,” they sang softly, minus Harry Styles, Zayn Malik, Liam Payne and Louis Tomlinson. “And you'll never treat yourself right, love, but I want you to.”

Both romantic ballads were hits on the Billboard Hot 100 back in their heyday, with 1D's recording of the song reaching No. 33 in 2013. “Lego House,” a single from Sheeran's debut album +, it reached No. 42 on the chart that same year.

The show comes on the second half of Horan's tour in support of his 2023 album The Showwhich peaked at No. 2 on the Billboard 200. The world trek kicked off in February with two shows in Belfast and will conclude on October 9 in Bogota, Colombia, after which the “Slow Hands” singer will have performed across Europe , Asia, North America and Latin America.

Sheeran is also touring across Europe, with his next show scheduled for Saturday in Romania. Sheeran's latest albums, – and Autumn Variationswhich were both released in 2023, peaked at No. 2 and 4 on the Billboard 200, respectively.
