George Clooney’s girlfriend Elisabetta Canalis has been implicated in a drugs-and-prostitution scandal in Milan. A French escort girl testified this week that she saw Canalis doing cocaine in a Milan nightclub that’s now the focus of an investigation into an alleged drug-fueled high-class hooker ring. Prosecutors say that call girls were paid in cash and drugs to encourage clients to buy expensive booze; the biggest spenders were allegedly given free cocaine and could buy sex from prostitutes. So far, the investigation has closed two venues, The Club and Hollywood, and five people have been arrested. Canalis’ alleged drug use took place in 2008, a year before she started dating Clooney, who owns a villa north of Milan.
