Rod Stewart has revealed his son was rushed to hospital after "going blue" while playing football. 

The Maggie May singer, 77, who is an avid Celtic supporter, said that his 11-year-old son Aiden had donned the Hoops to make his dad proud in a recent under-12s team.

But things took a drastic turn when the youngster suffered a bad panic attack and fell unconscious.

Speaking to FourFourTwo, Sir Rod said: "We thought my boy had a heart attack.

"He was going blue and was unconscious until he calmed down. It was scary, but it turned out to be a panic attack.

"The lad wanted to do well, pulled on the Hoops in Scotland for his dad.

Sir Rod added: "Another boy fell backwards and banged his head - he's still not back. In all of my days watching football, that's the only time two ambulances had been called."
