Did you know that there are over two million homeless teenagers in America? That's the bad news.
But here is some encouraging news: there's something you can do about it.
Demi Lovato is one of a number of celebrities (Kristen Bell, Julianne Hough) taking part in the Teen for Jeans campaign, which asks people to drop off used jeans at their local Aeropostale to be donated to shelters in your community.
In exchange, the school that donates the most pairs will receive $5,000 and Aeropostale pants for every single student! Seems like a no-brainer, doesn't it?
