The Paisley singer was an uncredited extra in Still Game, and even the cast had no idea.
The revelation came from Sanjeev Kohli, who played shopkeeper Navid Harrid in the BBC comedy, speaking with Jackie McNamara and Simon Donnelly on Not Another Football Podcast.
He said: “Paolo Nutini was in Still Game.
“It was before he was famous. He gets onto a bus, he’s about age 14.”
The moment appears in the episode “Courting”, which first aired on September 20, 2002, as the third episode of the first series.
The plot follows Jack asking out Barbara, a woman working in a charity shop, leaving his best friend Victor feeling lonely.
Winston, meanwhile, finds himself barred from The Clansman and forced to drink elsewhere.
Somewhere in the background of that Craiglang day, a future star was quietly getting off a bus.
At the time, Nutini was still a Paisley teenager expected to follow his father into the family business.
His family’s fish and chip shop, Castelvecchi, has been a fixture in the town for more than a century.

For Still Game fans, it is a small piece of Glasgow and Paisley history hiding in plain sight.
And for Kohli and the cast, a surprise more than two decades in the making.
Still Game itself later moved from television to sold-out live shows at Glasgow’s SSE Hydro, with a 21-night run in 2014 followed by 15 more dates in 2017.
