Paris Hilton has a new club

Paris Hilton reportedly smoked marijuana during a night with Mischa Barton's ex-boyfriend Cisco Adler at a Hollywood nightclub.The blonde heiress and Adler arrived at Guy's nightclub at 1am on Tuesday night where they were apparently seen hugging and "making out"as they reportedly smoked the drug. Paris took sips from Adler's drinks before performing a karaoke version of' Bette Davis Eyes' to help celebrate a friend's birthday. Fellow revellers also claim Paris sang along to the 4 Non Blondes song 'What's Up', replacing the "what's going on" chorus with "let's smoke a bowl!"Paris and Cisco left the club at 2.30am in separate cars. Paris' representative denies she smoked any drugs, but admitted: "She was with Cisco Tuesday night/Wednesday morning."Reports of Paris' drug taking come just a month after the 26-year-old told US chat show host Larry King she had never experimented with drugs . She also vowed to quit the Hollywood party scene after serving 23 days in prison in June for driving with a suspended licence.
