Rwanda.

The charitable organization sponsoring Hilton’s planned trip to the African nation, part of her aim to swap partying for philanthropy, said on Thursday it was postponing the journey.

The Spanish-based group, Playing for Good, said it was cancelling the trip due to a “restructuring” in its organization.

“Paris has been a loyal and gracious supporter of Playing for Good, but the foundation has to regrettably reschedule this trip,” the group said in a statement.

The group said it hoped to reschedule “at a later date.”

Earlier this month, the millionaire hotel heiress turned TV personality said in an interview in Newsweek magazine that she hoped to shed her party-girl image and leave a mark on the world. The Rwanda trip was to be a first step on that journey.

She told Newsweek that “before, my life was about having fun, going to parties — it was fantasy.”

“But when I had time to reflect, I felt empty inside. I want to leave a mark on the world,” Hilton said.

Playing for Good helps business and celebrities become involved in charity work. The group had hoped to videotape Hilton’s trip in the hope of selling a reality TV show called “The Philanthropist” featuring various celebrities.

Last week, Paris announced  her plans to live forever by having scientists freeze her body, in the company of that of her pets, after she dies. The heiress is investing a small fortune in the world’s biggest suspended animation cemetery at the Cryonics Institute in Michigan so it can preserve her and then bring her back to life.

                  “It’s so cool,” she says.

                    “Almost all the cells in the body are still alive when death is pronounced.”

                     “And if you’re immediately cooled, you can be perfectly preserved.”

                          “My life could be extended by hundreds and thousands of years.”
