Rod Stewart's Celtic fan credentials have never been up for debate.
The veteran rocker, and Hotline lover, has shed tears of joy, as well as despair, following the team he loves over the years.
And Sir Rod is never shy in getting involved in a singalong. The crooner gave his vocal chords a good stretch as he joined supporters in song during the 7-0 win over St Johnstone on Saturday.
The Hoops superfan was captured being taking over by the thrill of the win on the opening day of the season.
Stewart can be heard chanting "Here we go, 10-in-a-row", as he turns to the camera to hail Neil Lennon's side.
It's the perfect start to the season for the Premiership champions but another title victory this will take them to nine successive triumphs.
But supporters are allowed to look ahead and Sir Rod couldn't resist joining fans in song.
Watch the video above to see Sir Rod in full voice.
