Paris Hilton Mourns Her Friend!

Paris Hilton has never had a problem with the paparazzi, in fact she seems to rather like them, but yesterday she was noticeably irritated to see the cameras outside of her sister Nicky Hilton's house. Paris, who arrived together with Nicole Richie, was among the guests who had gathered at Nicky's house to remember their friend Casey Johnson who was found dead in her house yesterday. Paris and Nicky were childhood friends with Casey and are said to be distraught over the news of her death.
