JUSTIN TIMBERLAKE and rapper LUPE FIASCO have been recruited by pop singer KENNA to climb Mount Kilimanjaro this autumn (09) in a bid to raise money for charity. The trio will be joined by a team of adventurers assembled by Ethiopian-born Kenna as they scale the 19,000-foot (5,890 metre) African peak as part of a fundraising and awareness effort for the worldwide water crisis. The mammoth climb will serve as a personal triumph for Out of Control hitmaker Kenna, who almost lost his father to the water shortage. He tells America's Elle magazine, "My dad almost died as a child from waterborne diseases in Ethiopia, and he had talked to me about digging a well there, and I thought, 'I have too many friends who would be concerned with the subject of clean water. Maybe I can help out.'" And Fiasco insists he's ready for the challenge, which he plans to turn into a fun race with his pal: "I'm an adventure junkie. Part of the motivation is beating Kenna to the top. Sabotaging his tent, taking the lining out of his coat, lacing it with ants or something like that."
