A PAISLEY shopper who left his wallet at home was stunned when Scots singer Paolo Nutini saved the day by paying for his grocery bill.

Michael McCallum, 67, was left speechless in the town’s local Aldi after music star Paolo, 33, gallantly picked up his grocery tab.

Paolo was happy to help out

The retired technical author had gone to the shop on Neilston Road to pick up some extra food but was shocked when he found out at the till he’d forgotten his wallet.

But Paolo, who was in the queue behind him, saved the day by swooping in to pay for Michael’s £12.45 shop.

Michael said: “I was stunned, completely flabbergasted when this young guy in the queue said he was paying for my shopping.”

The dad-of-three didn’t recognise the music star immediately, describing him as “just an ordinary guy wearing a beanie hat”.

And when Michael asked the check-out saviour what his name was so he could repay him, the kindly stranger insisted his name was “Harlow”.

Only then did the shopper realise it was the best-selling singer Paolo Nutini who has topped the charts with albums including These Streets and Sunny Side Up.

Amazed at the celeb's kindness, Michael instinctively went to shake his hand before Paolo gently reminded him "you can't do that just now".

Michael added: “Even though I didn’t recognise him, he has proved himself to be the perfect gentleman.”
