Ed Sheeran's 'Galway Girl' has been revealed as Niamh Dunne - a fiddle player from Limerick.
The singer-songwriter's track, which is heavily influenced by Irish traditional music, has been topping the charts.
And the mystery lady who "played the fiddle in an Irish band" was about Niamh, who's a member of acclaimed Antrim-based folk group Beoga that collaborated with Sheeran on the track.
But it appears there's nothing more to it than artistic licence as Niamh is currently on honeymoon with her husband and fellow band-member Seán Óg Graham.
Modest Niamh told RTÉ Entertainment that she couldn't claim credit for the tune.
"I'm so happy with 'Galway Girl', Ed Sheeran knows how to write a great pop song and it's so catchy," she said.
"As for being the inspiration I dunno if you could go that far really, Christ almighty and I a Limerick woman.
"My sister said she knew straight away it couldn't be about me when later in the song she beats him at darts and pool," she laughed.
