Cathal Shortt proposed to Leanne Peoples as Ed played his hit Thinking Out Loud and she immediately said "yes".
Today FM witnessed the proposal and posted a video of the special moment to Facebook.
It's not the first time Ed has seen couples succumb to the romance of his gig with a young Irish couple getting engaged at Ed's concert in October last year.
Owen Byrne got down on bended knee while Ed Sheeran played the heartfelt ballad 'Show me Love' and asked Vickileigh Lawlor to be his wife.
"Just as he started giving her socks I got up and did my thing and the whole place went mental,” the Co Wexford man told Beat 102 103 FM at the time.
Vickileigh, his girlfriend of two years said yes, and several other concert goers caught it all on camera and sent the images to the happy couple.
