Jessica Biel will be joining her bf in a climb up Mt. Kilimanjaro in a bid to raise awareness for the global need for clean water.

Jessica & Justin (who announced his intent to do the hike last spring) will join Lupe Fiasco and Isabel Lucas on the African climb, according to the AP, organized by singer and producer Kenna.

“This is a basic human necessity that needs to be addressed now,” said Biel in a statement. She went on to say that she's participating in the climb “to help any way I can in order to raise awareness toward the life-threatening clean water crisis happening not only in Africa but around the world.”

Plus, who'd want to let their boyfriend hang out in the middle of nowhere that long with Isabel Lucas?
