"Paris Hilton's current problems related to her drug arrest and subsequent criminal charges are very much similar to the Lindsay Lohan story,” Pinsky told RadarOnline.com during an exclusive interview. “It's truly Lindsay Lohan's story in slow motion.”

Paris Hilton has been arrested on a cocaine charge in Las Vegas, RadarOnline.com has confirmed.

Police say the hotel heiress was arrested for possession of cocaine after officers stopped the car she was travelling in outside the Wynn hotel late on Friday night.

That car, a black Cadillac Escalade, was driven by Hilton's boyfriend Cy Waits, who was booked on suspicion of driving under the influence of drugs.

A spokesman says officers stopped the vehicle when they noticed what they suspected to be marijuana smoke coming from it.
