The singer, who rose to fame after appearing on Britain's Got Talent and singing I Dreamed A Dream, joined celebrities, including Darius Campbell, and television presenter Carol Smillie, for the Prince And Princess Of Wales Hospice 30th Anniversary Variety Performance.
Comedienne Karen Dunbar hosted the event, which was held at the Clyde Auditorium last night.
After performing Ms Boyle said: "I am honoured to have been asked to support the Prince And Princess Of Wales Hospice's Variety Performance and helping to raise money for the Brick by Brick Appeal, which will build a much-needed new hospice for Glasgow."
All proceeds went to the hospice's £15million Brick By Brick Appeal, which is supported by the Evening Times, to create a new facility next to Bellahouston Park.
Thousands of people flocked to the gala event to see opera act Amore, Gymtasia Evolution and a group from the The Royal Conservatoire of Scotland.
Barbara Bryceland, from BBC show The Voice, also took to the stage, while singers Tallia Storm and Owen Paul provided entertainment, along with comedian Craig Hill.
