Has Paris Hilton Returned to the, Um, Joint?

Has Paris "I Don't Do Drugs, Larry" Hilton fallen in with a bad crowd since being liberated from the hoosegow? Or perhaps she is researching a film role, à la Britney? Per the New York Post's Page Six, the Simple Lifer emerged the other night from an SUV parked outside a Hollywood hot spot awash in a haze of marijuana smoke. "She took a huge puff off a joint," says an eyewitness, "and exhaled the pot smoke basically in my face." Hilton's rep, perhaps busy banging his head on the desk, has yet to comment for the tab.
