Matt Damon is used to leading a quiet life away from the screen - so he was surprised when arguing paparazzi chased him and his girlfriend through the streets of Los Angeles.
The actor and girlfriend Luciana Barroso noticed they were being followed by two different sets of photographers, before the cameramen started arguing among themselves.
Damon, 33, says: "It was three in the afternoon and they were driving really fast on the wrong side of the road through school zones.
"I could see the headline: 'Child killed by idiots', so I slowed down to say: 'Guys, there's no need to rush.'
"It ended with one of the paparazzi cars crashing into the other and then they got out and started fighting, so we went home alone."
