Niall Horan soaked up the craic while he was on his home turf in Ireland for two concerts in Dublin over the weekend - and showed off a bit of that famous Irish hospitality while he was at it.

Horan, the former One Direction superstar from Co Westmeath who’s now enjoying a solo career, took his “The Show: Live on Tour” to Royal Hospital Kilmainham on Friday and Saturday night for two massive, sold-out gigs.

On Friday, Horan was joined on stage by pal Ed Sheeran and the two turned up the nostalgia when they broke out into “Little Things,” a song from Horan’s One Direction days that was actually written by Sheeran.

In a sweet gesture, Sheeran - who has pretty deep Irish roots - donned a 'Dublin Is For Lovers' top, an exclusive piece of merchandise from Horan's huge tour.

Afterward, Horan shared some behind-the-scenes snaps, one of which was him and Sheeran tucking into - what else? - pints of Guinness.

The pint likely wasn’t the last for Horan and Sheeran as the two headed for Hacienda Bar in Dublin afterward with some pals.

“Great to welcome Ed Sheeran and Niall Horan to the Hacienda last night,” the Dublin bar said on social media on Saturday.

“It was a wonderful night and it was also special to welcome James Blunt and Lewis Capaldi.”

The bar shared a picture of Sheeran and Horan with the owner of Hacienda Bar, Shay Duignan.

Hacienda Bar is no stranger to celebrity pop-ins. In June, Taylor Swift brought her entourage - including Travis Kelce, Stevie Nicks, and Paramore - there at the end of her sold-out run at Dublin's Aviva Stadium. Other recent visitors include Kal Penn, Cian Ducrot, and Olivia Rodrigo.

Also at the star-studded after party on Friday was Irish singer-songwriter Aaron Rowe, who shared this picture with Capaldi, Sheeran, and Blunt.

Horan's Irish hospitality didn't end on Friday, however.

Extra.ie revealed that Horan called Kehoe's in Dublin's City Center to ensure his favored snug was available for a few post-gig tipples on Saturday.

"Niall booked the snug so it was all hands on deck to get it spruced up for his arrival," said a well-placed source.

"He told the staff that Capaldi would be tagging along for a few beverages as well."

Keeping Horan’s favorite spot free was a tough gig for staff at Kehoe's as the popular Dublin haunt was packed to the rafters on Saturday night.

"Kehoe's was jammers. There were the usual Saturday night punters. Then the Yanks arrived en masse after the match as they wanted to make sure they got a taste of an ‘Oirish’ Dublin pub. So keeping the snug free was a task in itself," said the source.
