Friends and family of teenager Triona Priestley are determined to make her dying wish come true.
Triona, who is from Co Dublin in the Republic of Ireland, is in her final stages of battling cystic fibrosis and her dying wish is to meet her celebrity idol and favourite musician Ed Sheeran.
#SongForTri has been trending on Twitter since the weekend, as hundreds of Triona's loved ones join forces to try and contact the singer and make her wish happen.
15-year-old Triona is in Dublin’s Temple Street Children's Hospital Intensive Care Unit.
Yesterday, hundreds of her school friends gathered in Castleknock Community College in Dublin to sing for her.
A couple of close friends also made a YouTube video for Triona, to raise awareness for Cystic Fibrosis and to tell the teenager how much she meant to them. The soundtrack of the short video is Ed Sheeran's hit song Drunk.
