For actress Jessica Biel, there ain't no mountain high enough to keep her from supporting her man, Justin Timberlake.

The former N'Sync singer along with rapper Lupe Fiasco and singer Kenna, are taking Initiative to raise awareness for clean water needs worldwide by climbing Mount Kilimanjaro. And Jessica is jumping on board.

In an effort to help raise awareness toward the "life-threatening clean water crisis happening not only in Africa but around the world", the 7th Heaven star says she is addressing the problem by teaming up with Summit on the Summit.

The organization is dedicated to lessening the more than one  billion people worldwide who don't have access to safe, clean drinking water.

“This is a basic human necessity that needs to be addressed now,” Biel said.

The 27-year-old, who McAfee named the "Most Dangerous Celebrity in Cyberspace" earlier this year, is taking on the mountain of a challenge with vigor. Partner in climb, Justin Timberlake and Biel have been training to prepare for the physical intensity needed to take on Mount K.

"I've been training four times a week to get my VO2 [oxygen consumption] levels up to expand my lungs," E! Online reported the star as saying to GQ. 

"We'll climb for a week straight, carrying 30 pounds on our backs. It's going to be intense."

Trip organizer, Kenna, is paying respects of the trip to the near-death-by-waterborne-disease of his father for motivation. In a comment to the press, Kenna suggested Biel won't be the last of celebrity challengers who will make their ascent in January.

Until then, the clock on the website ticks down to final lift-off and Jessica Biel (and possibly others) will be cranking up their workouts to take their fitness and their charitable work to a higher level.
