Ben Affleck allowed his 10-year-old son behind the wheel of a Lamborghini. He promptly backed it into a BMW.

Samuel Affleck jumped in the driver seat with the engine running and shifted the Lamborghini into reverse. That’s a quarter-million-dollar mistake. Paparazzi caught it on video.

Photos from the scene show the back bumper kissing the driver-side panel of the BMW. Ben and Samuel and future step-mom Jennifer Lopez stepped out to view the damage. The dealer told TMZ that the cars were “close together,” but this wasn’t a fender-bender. However, the video does not lie.
