Wynn spokeswoman Jennifer Dunne said on Wednesday that Hilton won't be allowed at the properties anymore.
Dunne also says Cy Waits has been "separated" from his job as managing partner of the Tryst Nightclub at Wynn and XS The Nightclub at Encore.
Hilton was arrested on Friday for investigation of felony cocaine possession, and Waits was arrested on suspicion of misdemeanour driving under the influence.
Police say a bag containing 0.8 of a gram of cocaine fell from a purse carried by Hilton when she reached for lip balm. She says it was not her purse.
