Paris Hilton backs into car; leaves scene

Paris Hilton hit a parked car causing damage, then left without leaving a note -- a violation of California law, and it's all on video.

It happened Thursday after a shopping spree in trendy Robertson Blvd in L.A. with her new BFF, Kim Kardashian . After loading her shopping bags into the trunk of her Range Rover, Hilton says good-bye to Kardashian and starts to back out of the parking spot without her seat belt on -- another violation of law.

Hilton checks her mirrors and looks around, but apparently doesn't notice the parked Honda Civic behind her and slams into the bumper, causing damage to both vehicles.

Hilton then exits the public parking structure without leaving a note with her contact information, which is a misdemeanor under California law, punishable by as much as six months in jail.
