Sir Rod Stewart flashed the middle finger at the Celtic v Motherwell football match at Celtic Park on Saturday.
The stylish rocker, 78, was suited and booted and wore a long camel-coloured coat with a white shirt and brown cardigan.
However, the star of the Grammy Award-winner’s outfit was his bright green tie, which he wore proudly with a gold ‘Celtic’ pin.
Rod had a few words with the security as he left his car and prepared to head into the busy stadium.
On his way inside the building, Rod gave onlookers a brown-gloved middle finger with a smile on his face.

Rod’s gesture was in response to boos by Celtic ultra fans The Green Brigade.
The banned fan group launched a ‘day of action’ for Saturday’s clash by gathering on the Celtic Way amid their lengthy absence from inside the stadium.
Celtic has banned the ultras fan group from all home and away matches due to what the club branded as ‘unacceptable behaviour’.
Sir Rod was booed as he entered the ground after he previously blasted a group of fans who disrupted the minute’s silence on Remembrance Sunday before a match against Aberdeen.
Rod is a lifelong supporter of Celtic and got the club’s crest tattooed onto his arm.
He got the tattoo during the Australian leg of his Rod Stewart The Hits tour which he has been on since 2021.
Rod was recently among the host of A List celebrities who attended the Las Vegas Grand Prix.
He pulled a funny face as he sat down with Gordon Ramsay, who had just become a father for the sixth time.
They had much to talk about as Rod has eight children of his own: Sarah Streeter, 60, Kimberly Stewart, 44, Sean Stewart, 43, Ruby Stewart, 36, Renee Stewart, 31, Liam Stewart, 29, Alastair Stewart, 17, and Aiden Stewart, 12.
Alastair and Aiden are Rod’s sons with his third and current wife Penny Lancaster-Stewart, to whom he has been married since 2007.
