Matt Damon As Santa Claus For Water.org (VIDEO)

Celebrities are often known for their extravagant lifestyles but not Matt Damon.

This holiday season he is teaming up with Water.org, the charity he co-founded, to launching a water bottle campaign to help over 884 million people who lack access to clean, safe water.

The "We Bought A Zoo" star isn't out of touch, however. He knows how present-obsessed kids can be so he put on a Santa suit and set off to convince the children of America that water is the greatest gift of all.

Also, after his last brush with a youngster, it looks like the star is trying get his name out to a more youthful audience.

Check out the video above of the water-bottle peddling Damon.
