Jessica Biel, Lupe Fiasco Premiere MTV's 'Summit' At The Tribeca Grand

[All photos by Ben Gabbe for PMc] Jessica Biel secured her spot in Justin Timberlake's heart by proving she is an independent woman, mkay?  Remember that whole press summit to Mt. Kilimanjaro? Yeah, the film documenting the trip is out.... Emile Hirsch and Kenna showed up to the Tribeca Grand Hotel last night for the premiere of Summit on the Summit: Kilimanjaro. The MTV documentary will show the celebs break a sweat while climbing Africa's highest mountain.

The trek was for a good cause (of course). Their goal is to raise awareness for the global clean-water crisis. Also climbing for the mission were Lupe Fiasco, Santigold and Isabel Lucas.

Jessica Biel spoke to MTV News about the crazy ordeal. "I was sort of irritated that we were stopping so much, I said to one of our guides, 'Can we go a little faster?' " she says. "And then I got a little bit irritated, and I started going down this little area, kind of pissed off, and then I immediately got nausea. The mountain was like, 'Don't disrespect me.'"

If you want to check it out, Summit on the Summit: Kilimanjaro premieres on Sunday at 9 on MTV.
