As part of her post-prison image rehab, Paris Hilton was planning a November trip to Rwanda to highlight the crisis there as well as her new-found philanthropy. But the heiress is going to have to wait a little longer to follow in Angelina Jolie's footsteps. The Playing for Good Foundation, which proposed the Africa trip to Paris, is restructuring. "Paris has been a loyal and gracious supporter of Playing for Good, but the foundation has to regrettably reschedule this trip," the organization said in a statement. "Playing for Good... is looking forward to rescheduling the trip with her at a later time."
