The music stars appeared on the city’s Grafton Street and treated passers-by to a few songs.
They were joined by musician Jacob Koopman for the impromptu set on the iconic thoroughfare
Along with some of their own songs, such as Horan’s Slows Hands and Capaldi’s number one hit Before You Go, the pair also did their own rendition of Coldplay’s classic, Yellow.

Unsurprisingly, the impromptu set gathered quite the crowd, who were enjoying every second.
A busking performance that you’d definitely not ignore.
It seems like the former One Direction singer is enjoying his time in the Irish capital with the Scottish star.

The pair were also spotted outside the Guinness brewery, with Capaldi deciding to carry Horan in his arms and posing with each other
The two have been friends for several years, having first met in 2018, when Horan invited the Scot to perform at a gig in Glasgow with him. Capaldi went on to support the Irish singer on his Nice to Meet Ya world tour in 2020.
