Justin, Lupe to climb Mt. Kilimanjaro

The singers will be amongst other adventurers to mount the 19,000-foot African peak as part of the effort to create awareness for the global water crisis.

Kenna, co-ordinator for the giant ascend, revealed it would further fulfill a personal but a noble ambition.

"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," Contactmusic quoted him as telling Elle magazine.

Meanwhile, Fiasco insisted he was looking forward to playing mischief-maker.

He said: "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."
