Rod Stewart's 11-year-old son, Aiden, was rushed to the hospital in an ambulance after collapsing during a soccer game.
Things initially looked fairly grim and quite serious, but Rod eventually confirmed that Aiden suffered a panic attack.
"We thought my boy had a heart attack," he told FourFourTwo. "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," Rod, 77, added.
The "Forever Young" singer noted that another incident happened at his son's game as well.
"Another boy fell backwards and banged his head — he's still not back," the Grammy winner said. "In all of my days watching football, that's the only time two ambulances had been called."
It's not known when the incident happened, as Rod didn't disclose those details.
Aiden is one of Rod's eight children; he shares the boy and brother Alastair, 17, with his current wife, Penny Lancaster-Stewart. Rod is also the father to daughter Sarah, 59, daughter Kimberly, 43, son Sean, 42, daughter Ruby, 35, daughter Renee, 30, and son Liam, 28.
