Courtney Wagner was arrested at the property in Malibu, California last month (Apr12) after officers responding to reports of a gunshot allegedly found heroin and cocaine.

She faced charges of drug possession but editors at TMZ.com now report the case will be dropped as cops did not have a warrant for a drugs raid, in violation of the Constitution's Fourth Amendment.

The L.A. County District Attorney tells the website, ""Deputies did not have probable cause, consent, nor a warrant to conduct the search and recover narcotics so as a result the case is being rejected because of illegal search and seizure.""
