Snooki was in Florence, Italy on Monday and driving when she struck the cop car.
In a report by TMZ, Snooki reportedly smacked right into the back of the patrol car, wedging her ride between the car and a highway protection wall. The witness says Deena was in the passenger seat at the time of the crash - and when she tried to exit the car, she had to go through the window because the door was blocked by the wall.
But witness tells TMZ that "zero alcohol was involved." No one was also reportedly got injured.
The Jersey Shore star was taken in the custody of authorities but it can't be considered a formal arrest.
