Rock legend Sir Rod Stewart launched into a furious verbal onslaught against radio star Simon Jordan, demanding he "shut the f*** up".
The Maggie May singer took to Instagram Stories to post a statement arguing against the TalkSport pundit's recent remarks about Scottish football.
It came after former Crystal Palace owner Jordan made "disrespectful" comments about the likes of Celtic and Rangers.
Stewart, 79, a Celtic Football Club fan, didn't hold back as he addressed the subject.
In view of his 1.4 million Instagram followers, he penned: "I'm absolutely sick and tired of the constant deriding and disrespect of Scottish football shown down south....especially by one Mr Simon 'motor mouth' Jordan (who I'm sure has had elocution lessons in the past)."
He went on to add: "It's our game, we know it's not the EPL or La Liga but it's our game and I love it.

"So back off Mr Jordan, and by the way, what did you achieve at Crystal Palace? With all due respect to Palace of course."
Going on to mention former Scottish footballer and manager Graeme Souness over his recent TalkSport appearance, he added: "One thing Graeme Souness quite rightly pointed out the other day on TalkSport... if Celtic or Rangers were in the Championship with the money that's dished out by Sky etc it would only be a couple of years and we would be able to compete, no doubt about that.
"So shut the f*** up Jordan, and leave Scottish football alone."
The rant came after a heated discussion between Jordan and Souness over Scottish football clubs Rangers and Celtic.
"You look at Rangers and Celtic, first of all, Celtic are going to win the league by being the best of a bad bunch, neither of these sides are outstanding," Jordan remarked.
He added: "I would look at once upon a time the argument of Celtic and Rangers coming down to English football would make a splash in English football, they wouldn't.
"They'd struggle in the Championship these two sides right now. I think they're both poor sides."
Football fan Stewart surprised crowds at a Glasgow pub last month when he lead an unexpected sing-along.
