Hilton was arrested on Friday night for allegedly possessing cocaine in her purse, according to the Las Vegas Police Department.

Both Hilton and the driver were arrested, the report said.

This was not the first time that Hilton was taken into custody for allegedly possessing drugs.

During the soccer World Cup this summer in South Africa, Hilton was booked into jail for allegedly possessing marijuana, but the case was quickly dropped.

It's unclear when Las Vegas prosecutors will decide whether to charge Hilton in the cocaine case.

A great-granddaughter of Conrad Hilton, founder of Hilton Hotels, the junior Hilton is an American socialite, heiress and media personality.
