Rod Stewart was not holding back on the celebrations following Celtic's victory in the Viaplay Cup Final showdown which took place at Glasgow's Hampden park over the weekend.
The Hoops secured a 2-1 victory over Rangers on Sunday, with a Kyogo double securing the first silverware of the season for Ange Postecoglou's side.
The weekend celebrations were in full swing for the Celtic-daft rocker as his son Alastair shared videos of the celebrations in Glasgow's Murphy's Irish bar on his Instagram.
The Maggie May singer can be seen belting out the infamous tune along with fans and putting his hands in the air as he wrapped a Celtic scarf around him.
However, when many fans sang the sweary dig at their opponents, Rod giggled as he missed out the words.
The British rocker is a well-known fan of the club, with the 78-year-old regularly taking family trips to Glasgow's east end to watch the game which of course came as little surprise that he had to be in Hampden to celebrate the occasion.
We reported recently how the Baby Jane singer recently attended Celtic Park alongside his three children, Alastair, Liam and daughter Renee. Liam's pregnant girlfriend also joined them which saw Celtic claim victory 3-0 over Livingston.
Meanwhile, Sir Rod Stewart has announced that he's added another date to his Edinburgh Castle gig this summer due to high demand.
The Maggie May singer toured last year and added a series of dates to continue his successful run and the two shows in the capital will finish off his summer tour on Thursday, July 6 and 7, and tickets can be found here.
The six new gigs will see Rod head to the capital as well as Bristol, Hull, Durham, Northampton and Plymouth. The rocker said he was excited for the summer so he can perform under the stars.
Speaking about the new dates, Rod said: "My favourite memories have been summer nights with a beer or two alongside the best fans in the world, I'm impatiently awaiting this summer playing at a variety of special venues - football, cricket and rugby stadiums, estates and castles! We'll all be dancing under the stars."
Rod's Edinburgh Castle gig will be the first he's played there in 13 years.
