Sir Rod Stewart left fans stunned after he was spotted giving a helping hand to security at Parkhead stadium tonight.
The Maggie May singer watched on as Celtic took an impressive 4-2 win against Dundee United before he signed autographs for lucky fans as he helped the security team clear fences.
Fans who waited outside the stadium to get a look at their victorious players were left shocked after seeing the 77-year-old chart-topper alongside the crew. As well as the all important football, the Hoops daft singer actually has another reason to be in Glasgow this weekend as he is set to be honoured at the Scottish Music Awards.
