Bob Geldof is facing legal action from a motorcyclist who was injured in a collision with the star's car in 2007.
The rocker was involved in an accident in London three years ago, when his vehicle collided with Andrew Quinn's bike.
The 42 year old claims his knee was shattered in two places in the smash, and he has been left with permanent damage.
Quinn filed a lawsuit at London's High Court on Tuesday (13Apr10) seeking $450,000 (£300,000) in damages from the musician.
He says, "I hit the brakes but there was no way I could stop. I flew through the air thinking, 'This is going to hurt.' It was agony. I was only aware of a mop of hair staring down. In the ambulance the police gave me his details and I realised who it was.
"The injuries may be with me for the rest of my life."
But Geldof insists he is baffled by the legal action - because he believed the case had already been closed.
He says, "This is the first I have heard about it. I thought the matter had been resolved by the insurance firm."
