JT's one of the good guys...

Not only does he have the sexiest voice, and moves, and body, and... ok, we'll stop. Not only is Justin Timberlake pretty alright, he's got a selfless, caring, kind side too. Ahhhh.

In aid of fundraising and awareness of the worldwide water crisis, JT has volunteered to climb Mount Kilimanjaro in January. Yep, all 19,000ft(!!!) of it. Rather him than us!

And Jessica Biel, the lucky lady, will be joining him. How romantic.

The vomit-inducingly cute couple decided to do the climb after being astonished that more than a billion people in the world have no access to drinkable water. And Jessica, speaking out on this shocking statistic, said, "This is a basic human necessity that needs to be addressed now. (I want) 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."

Well good on you both! Hopefully Justin will be working up a sweat for the most part and have to take his shirt off. And hopefully there'll be pictures. Yeah...

If JT invited you, would you be climbing up Mount Kilimanjaro with him? Need we ask? Comments please...
