It was another busy day for reporters covering the Paris Hilton saga, with the news that she has been dumped by her agent and a prison visit from parents Rick and Kathy. The Hiltons spent about half an hour with their daughter through visiting room glass. "It's tough in there. It's cold," Kathy Hilton told reporters on her way out. "It's just good to see her. She was very happy. She wants to just do her time and get on with it. She really hasn't had much sleep," Mrs. Hilton added, in addition to losing her appetite. According to a source, the heiress was dropped by her talent agent at Endeavor agency, who told People mag, "Paris is no longer a client," but did not provide specifics. After being repped by the agency for two years, her split from the group was reportedly announced in a company-wide email.
