Celtic superfan Rod Stewart celebrated his first Old Firm game with his young son Aiden as a birthday treat.

The youngster, who was celebrating his sixth birthday, was treated to a Celtic v Rangers match on Sunday afternoon with his Hoops-mad dad. 

Pictures of the pair were posted on wife Penny Lancaster's Instagram page.

Rod, 72, shares two sons with Penny, 45, with Aiden's older brother Alastair also in attendance. 

Clad in Celtic scarves, the pair watched as the Hoops drew 1-1 against Rangers. 

The outing comes two months after Rod had a good old time to himself while helping to pick the fixtures for the next round of the Scottish Cup back in January. 

The crooner had a lot of fun with a bag of balls. And we loved it.
