Stars ready for last push to the peak of Kilimanjaro

Jessica Biel, Emile Hirsch, Lupe Fiasco and Santigold star Santi White are among the group hoping to raise cash and awareness about the world’s chronic water shortage by signing up for the charity climb to the 19,340-foot (5,895-metre) peak.

The Summit on the Summit posse set off on Thursday (07Jan10) and have been using the latest social networking technology to update fans and followers along the way.

In a recent ‘tweet’, climber Alexandra Costeau – the granddaughter of adventurer Jacques Costeau – writes, “2morrow we summit at dawn!”

And singer Kenna – the celebrity behind the big climb idea – adds, “Morning of. Actually slept. Can’t believe it. This is it. This is the last day. We feel the Love.”
