Lupe Fiasco

*After a torrential rainfall threatened to stall a gaggle of celebs climbing 19,340–foot Mt. Kilimanjaro, Africa’s tallest peak, Grammy-nominated singer Kenna, rapper Lupe Fiasco and singer Santigold literally broke out in song.

Climbing to raise awareness of the global water crisis, the celebrities took seven hours to reach 13,600 feet and eventually joined 200 locals for a singing contest between two teams of climbers.

“We had two groups singing and dancing back and forth,” Elizabeth Gore of the United Nations Foundation told People.com by satellite phone. “When you have these great African voices and the likes of Kenna and these other musicians, it was pretty awesome. It was really, really fun.”

Other famous faces on the climb include Jessica Biel, Alexandra Cousteau, granddaughter of ocean explorer Jacques Cousteau, and Kick Kennedy, environmentalist and granddaughter of Robert F. Kennedy.

The group plans to reach the summit on Jan. 12. At press time, a trip was planned to the UNHCR refugee camp in Ethiopia for a first-hand look at the water crisis followed by a visit to the village where Ethiopian-born Kenna’s family grew up and where his uncle died of a waterborne illness.
