Zach Bryan took the stage for 3 shows over the weekend in Dublin's Phoenix Park and treated fans to a big surprise at the last show.
At the last live show on Sunday evening, the country music star brought out Irish fan-favourite Dermot Kennedy!
Fans flocked to social media to rave about the surprise as fans seemed so surprised by the cameo from Irish man.
Over the three shows, organisers say that up to 180,000 fans were expected to go see Bryan over the course of the weekend.
Fans on social media can't stop taking about the gigs and the big surprise with one fan raging they swapped the nights they were going and missed Dermot Kennedy:
"I had tickets for tonight but swapped them for Friday night instead. Absolutely gutted I missed Dermot!!"
Another fan is trying to get over the concert hangover:
"Is there anything that hits worse than post concert depression.
Back to reality.
Had a great night though. Zach Bryan was incredible. He even brought out Dermot Kennedy. Thanks to everyone for the lovely comments.
Not sure I'll ever recover from this."
Another fan wrote:
"Just left and I have to say they put on some show "
