Kasabian frontman Tom Meighan was involved in a "freak accident" which saw him run down his father.
The rocker - who does not yet have a driving license - was told to release the car's handbrake by his dad, but ended up pressing down on the accelerator, and Tom Senior had to be rushed to hospital.
The singer told the Daily Mirror newspaper: "It was a freak accident, it was horrible. That was the worst day of my life.
"I can drive but it was in an automatic car. It was too fast. It was a real shock at the time ... It would only happen to me ... We have laughed about it now and that's all you can do.
"I'm very close to my dad. He's a very amazing person to have around, so that happening was awful."
Meanwhile, Tom Junior revealed his own injury, admitting he suffers from tinnitus - hearing ringing in the ears when no sound is actually present - after years of touring and loud music.
He added: "I've got tinnitus in both ears. It's my own fault though. I did it to myself. You've just got to try and shut it off."
