Not a great idea to tell someone who caused a fatal accident to drive safely. Well maybe it is a good idea, but not if you're a photog trying to engage a celebrity.

So imagine the moment when a pap told Rebecca Gayheart yesterday to "drive safely." Remember, back in 2001, Gayheart was driving when she struck and killed a nine year old boy. She was prosecuted for vehicular manslaughter and pleaded no contest. She was placed on three years probation and settled a wrongful-death lawsuit out of court.

Watch the video and squirm.
