Paris Hilton has been banned from the Las Vegas resort where she was allegedly caught in possession of cocaine last week.
The socialite and her boyfriend Cy Waits were driving along Sin City's famous Strip when their car was pulled over by cops, who chose to search the vehicle after allegedly smelling marijuana coming from the vehicle.
Waits was arrested on suspicion of driving under the influence and Hilton asked police to escort her into the nearby Wynn resort, so she could relieve herself.

Suspicious police officers insisted the celebrity place her purse on a table in a security room, prompting Hilton to ask if she could retrieve her lip balm.
Lt. Dennis Flynn of the Las Vegas Metropolitan Police Department says, "As she began to open it, I saw a small (stash) of what I believed to be cocaine in a clear baggy begin to fall from the purse and into my hand."
Hilton told the officer the cocaine was not hers and she thought it was gum.

She was subsequently detained under suspicion of cocaine possession.
And now Wynn spokeswoman Jennifer Dunne insists the hotel heiress will no longer be permitted inside Wynn Las Vegas properties.
The ban comes days after nightclub boss Waits was reportedly fired from his job as managing partner of the Tryst Nightclub at Wynn and XS The Nightclub at Encore, another Wynn resort.
Hilton faces up to four years in prison and a $5,000fine after prosecutors in Clark County, Nevada charged her with felony possession of a controlled substance on Tuesday.
The socialite will return to Las Vegas on Oct. 27 for arraignment.
