LOS ANGELES, Aug 28 — Socialite Paris Hilton was arrested in Las Vegas last night and charged with cocaine possession, celebrity website TMZ reported today.

Hilton, 29, a former reality TV star, was arrested after a traffic stop by police in which an undisclosed amount of cocaine was allegedly found in her purse, the website said.

Hilton (picture) was a passenger in the car; the unidentified driver was charged with driving under the influence.

Hilton was released from jail early this morning, the website reported.

Hilton, the great-granddaughter of Hilton hotels founder Conrad Hilton, has worked as a model, singer, actress, fashion designer and reality TV star. She runs multimillion-dollar businesses based on her name including clothing lines, fragrances and wine.

She spent three weeks in a Los Angeles jail in 2007 for violating her probation in an earlier reckless driving charge. — Reuters
