Susan Boyle made a surprise appearance at a Glasgow show this weekend. 

Susan, who rose to fame in 2009 after appearing on the third series of Britain's Got Talent, joined Donny Osmond on the OVO Hydro stage on Sunday, much to attendees' delight. 

Donny, known for hits such as I'll Make A Man Out Of You, took to the West End stage as part of his ongoing UK tour.

Taking to X, he wrote: "In Glasgow, Scotland and low and behold, guess who showed up to my concert? My dear friend, Susan Boyle!

"She was waiting in one of the dressing rooms backstage to go out to the audience and I heard this angel voice in the hallway. I walked up to the door and...."

Fans were left delighted by the cross-over. 

One person wrote: "She loves you as much as we do! Love Susan and she does have an angelic voice! She looks lovely. You're not bad looking either."

Another added: "Loved the show Donny. Susan is our treasure."

While a third said: "Lovely to see you both together in Glasgow xx"
