If there's one Gossip Girl kid who understands homelessness, it's the beautiful Nate Archibald. After the Captain went corrupt, Nate ended up squatting in his Upper East Side townhouse without water or electricity. Ok, it's not quite living on the street, but Nate is the most down to earth of any of them. And he may play a beautiful little rich kid on TV, but in the real world, Chace Crawford still understands the importance of giving to those less fortunate.

In Do Something's latest PSA, we corralled the uber-hottie to speak on behalf of Teens For Jeans-- a national campaign launced by Do Something in collaboration with Aeropostale--which asks young people to donate their jeans for homeless teens.

This is all you gotta do: drop off any pair of gently worn jeans to any Aeropostale store, who will then donate the jeans to a local homeless shelter for you!! And in addition to good karma, they'll give you 25% off a new pair of jeans. But don't listen to us, let Chace give you all the good deets above!!

Last year, we collected over 125,000 pairs of jeans. But Do Something is looking to double that number in 2009...so start now! Start at home and purge your closet of the jeans you never wear. Trust us. Gossip Girl will thank you.
