There's few things us Irish people like talking about more than celebrity spotting on this island!
Fans of the Mamma Mia films were star-struck when they walked into a pub in Co. Mayo and saw the actor who played Sky giving it socks on the karaoke machine.
@alannakingg Highlight of the weekend was seeing Dominic Cooper in one of the locals. #mommamia#dominiccooper#belmullet#sky#Ireland ♬ Lay All Your Love On Me - From 'Mamma Mia!' Original Motion Picture Soundtrack - Dominic Cooper & Amanda Seyfried
The 45-year-old actor is currently in Ireland as he's here filming a new movie about the Irish Civil War.
Shooting of the film has already begun in Ballyglass Lighthouse and also stars Irish actors Aidan Quinn and Sarah Bolger.
Called Cry, the film follows the story of an Irish lighthouse keeper who chooses to live a life of isolation as punishment for a tragedy he feels he should have prevented.
Sounds cheery! No wonder he needed a bit of karaoke to lift his spirits 😂
