Who's Been Digging Through Paris Hilton's Garbage?

After a long day of shopping, Paris was just about to head out to Sherman Oaks for a birthday party (after showing off the Gwen Stefani doll she'd planned to give the birthday girl as a present and thanking one of the paparazzi for catching her cat after it escaped the other day) when one of the photogs dropped a bomb on her: they'd seen someone going through the garbage cans outside Paris' house! Paris seemed understandably concerned by the news, asking the shutterbug to talk to her assistant about the mysterious trash thief - although in true Hilton fashion, she didn't let the scary news deter her from heading out to party until 2 AM!
