Rwanda will have to wait for Paris Hilton`s help. "Due to the restructuring of the Playing for Good Foundation, the philanthropic trip to Rwanda that the foundation had previously planned with Paris has been postponed," the children`s charity said Thursday in a statement. A staffer for Andy Gelb, a spokesman for the organization, said he was unavailable for comment. The 26-year-old socialite - who has promised to use her celebrity status for good causes - was supposed to pack her bags for the African country next month. On her itinerary: visits to schools and health-care clinics. "I`m scared, yeah. I`ve heard it`s really dangerous," Hilton told Newsweek magazine earlier this month. "I`ve never been on a trip like this before." Hilton announced the mission in September, several months after serving a 23-day jail sentence for violating probation in an alcohol-related reckless driving case. "There are a lot of bad people in L.A. Before, my life was about having fun, going to parties - it was a fantasy," she told Newsweek. "But when I had time to reflect, I felt empty inside. I want to leave a mark on the world."
