LEGENDARY singer Rod Stewart popped into a popular Glasgow pub after the Celtic game yesterday.

The 77-year-old, who watched his beloved Celtic draw with Rangers at Parkhead earlier in the day, was spotted at the Dirty Duchess on Argyle Street.

It seemed he had become a 'spare bartender' for the night as he was not seen enjoying a drink but rather working behind the bar and giving the staff a hand.

He could be seen chatting to a punter while a glass of beer and Guinness was next to him. 

The Dirty Duchess team posted on their social media: "Great to have spare bartender Rod ‘the mod’ Stewart tonight! #discoshifter #robstewart #mondown."

This appearance comes just days after the Maggie May singer was spotted at Murphy's, an Irish bar in the city centre.
