When she isn’t wearing a suit of body paint for SoBe Lifewater, Twilight bombshell Ashley Greene is joining forces with Justin Long — best known as “The Mac Guy” — for a new series of video PSAs promoting TeensForJeans.com, a non-profit charity organization for homeless and impoverished youth.

Between Jan. 19 and Feb. 14, drop off any pair of gently worn jeans to any Aéropostale store and Teens For Jeans will make sure they get donated to a local homeless shelter or charity. And just to says thanks, Aéropostale will give you an additional 25% off your next pair of jeans!
